Disclaimer: I do not own Owari no Seraph (Seraph of the End). I write this for your enjoyment only. I originally intended to cover fem!Yuu's life underground with the other Hyakuya orphans in Sanguinem in one chapter but it's turning out longer than I expected so I've decided to split it in two. Once again, I would like to thank my beta reader and editor, ResidentialPsycho, for her help in making this fic possible. Enjoy!
Chapter 3: A Life Underground
"Director, what's wrong?!" Mika cried as he soon as he saw the elderly woman hit the floor. Frightened, the other children got onto their knees, shaking the director in an attempt to wake her up but she would not move no matter what they did.
Akane placed her hand on the elderly woman's chest and gasped when she could not feel her heartbeat or any air coming through her nose or mouth.
"She's not breathing!" the young brunette girl exclaimed, her brown eyes wide with fear.
When Yuu realized her orphanage sister was right, she turned to Mika and asked:
"What are we going to do? We gotta help her!"
As soon as they heard Yuu's question, the others also turned to the blond boy, expecting him to tell them what to do as their "leader". And although he was just as frightened and confused as the rest of them, Mikaela forced himself to remain as calm as possible to keep a full-blown panic from breaking out among the younger kids since that was the last thing they needed right now. So he said the most rational thing he could think of:
"Yuu, call 911 quick!"
Yuichiro didn't need to be told twice as she quickly ran to the phone on the kitchen counter and dialed the number her parents and grandmother taught her to remember in case of emergencies but found to her horror that there was no one picking up on the other side.
"There's no one there!" Yuu cried.
As soon as Mika heard that, he knew there was something horribly wrong for he was told that there must always be people available to take emergency calls twenty-four seven. Not only that, he also noticed that the director's body was cold and stiff which told him that she most likely already dead. But he did not want the other kids to lose hope yet and suggested the next best thing he could think of:
"We'll go for help! Everyone, follow me!"
Yuu, Akane, and the others did not argue and quickly placed a blanket over their elderly caretaker's body before opening the door to the orphanage and running out together. Nothing could have prepared them for what they saw as soon as they set foot outside:
Absolute chaos.
The orphans gasped and watched in horror as cars crashed and piled up on top of each other as well as people screaming and dropping in the streets like flies. Like the orphanage director, they also had blood coming out of their mouths and noses, staining the ground crimson as their faces became forever frozen in pain and terror, never knowing what hit them or why.
"Oh, my god, what's happening?!" Akane cried as she tried to shield Taichi and Fumie from the horrid sight of a car spinning out of control and hitting a man who had just begun to fall from whatever it was that was killing the other people around them while Kouta shielded his eyes in shock and terror. Likewise, Yuu and Mika instinctively pulled Aiko and Chihiro behind them even though the sight of the dead man's body flying through the air like a rag-doll made them want to throw up themselves; they had to be strong for the sake of their younger brothers and sisters.
As the eldest and smartest child in the group, Mikaela knew for certain that there was nothing he or any of his fellow orphans could do for their elderly caretaker now. Whatever killed her was obviously affecting everyone outside as well and his first instinct and priority were to take Yuu, Akane, and the others to safety. Where they would go, he had no idea, but they certainly couldn't stay where they were at the moment; it was far too dangerous.
Thinking quickly, Mika hoisted Chihiro onto his back and made a gesture for Yuu to do the same with Aiko. Taking the hint, Akane quickly took Taichi and Fumie's hands tightly in her own. Kouta, who was the fourth eldest child, did not need to be carried or led by the hand. Mika knew the younger boy would have no problems following on his own and as soon as he made sure the group was secure, instructed them to follow his lead, repeating the words he said when they originally intended to go get help for their caretaker.
"Everyone, follow me!"
"Wait, what about the director?!" Yuu protested.
"I'm sorry, Yuu-chan, but we can't help her, she's dead!"
"But…!" Yuu began but Akane quickly cut her off.
"No, Mika's right, Yuu! The director wasn't breathing and I couldn't feel her heartbeat! The only thing we can do now is go someplace safe; that's what she would want us to do if she was still here!"
As much as she wanted to argue, she knew Akane was right and reluctantly nodded.
"Alright".
Without another word, Mika made a gesture and took off into the streets after making sure Chihiro was secure on his back. As soon as they saw their "leader" move, Yuu and the other orphans followed suit. Before he was finally sent to live at the Hyakuya Orphanage by his "uncle", Mika had been out and about the city a bit so he at least knew his way around the local neighborhood. His plan was to find someplace safe for his little family to stay until the chaos surrounding them blew over. Then he would think of what to do next.
As the orphans made their way through the neighborhood, they saw more and more people collapsing, some even throwing up their innards before dying while begging for help. While they were passing through a local shopping center, Yuichiro paused briefly in front of a bakery where she saw another victim of the unknown plague stagger outside. As soon as the man saw the disguised little girl, he opened his mouth as if to plead for her help but he too, started bleeding from every orifice in his body before dropping dead at the entrance. Yuichiro felt terrible but knew that there was nothing she could do for the unfortunate shopkeeper and quickly left him to catch up with Mika and the others, especially after Aiko had fainted on her back from fright.
As soon as she rejoined the others, Yuichiro noticed that they weren't alone.
"Mika, look! There are people over there!" she pointed out.
The blond looked in the direction of her gesture and saw that there were indeed groups of people who seemed unaffected by the epidemic, walking the streets. But he could tell right away that these were not normal people for they were clad in hooded black cloaks and moved in a robotic fashion. The only exception was their leader, who appeared to be a young girl with long, flowing rose-pink hair. She too, was clad in black but her attire was different from that of her followers. *1*
"Should we ask them for help?" Kouta suggested.
Mika shook his head. "No, I don't think that's a good idea, Kouta. They look dangerous to me, we can't trust them."
"Then what are we going to do?!" Yuu demanded, a little louder than she intended. At the sound of her voice, one of the strange hooded figures turned in her direction before making a gesture to the others with him.
Realizing that they have been spotted, Mika cursed.
"Crap, they saw us! We gotta hide!" This time, the other orphans did not argue, especially Yuu, since she knew it was her fault they got noticed.
"Where should we go?" Akane asked, her voice rising in panic as she drew Taichi and Fumie closer to her.
Looking around quickly, Mika spotted a possibly unused office building that wasn't blocked off by corpses or crashed cars.
"Over there!" he cried. "Everybody, get inside quick!"
No one wasted any time and ran towards the empty building as fast as their legs could carry them while jumping over corpses and debris on the streets. No doubt, their pursuers will follow but Mikaela hoped that he would be able to protect the other orphans by having them hide and lock themselves inside the rooms until the scary-looking people gave up and left.
Once everyone was inside, Mika and Yuu quickly locked the doors while Akane and Kouta locked the windows on the first floor. As soon as they were finished, Mika instructed everyone to go upstairs. He wasn't sure if locking the doors and windows would be enough to stop their unnatural pursuers but it might at least buy them some time. As the orphans made their way upstairs, they heard an announcement over the building's intercom system which also sounded like it was coming from every audio system in the city outside as well.
"Your attention, please: a deadly virus has been unleashed upon your city. There is no cure. However, we have chosen to spare the young- the virus will not affect anyone age thirteen or younger. Under the direct order of the Third Progenitor, Krul Tepes, we will collect the surviving children. From this day forth, you shall be under our protection." *2*
The strange announcement ended when the kids finally found a room large enough for all of them to hide in. As soon as they were inside, Mika and Yuu put Chihiro and Aiko down and quickly barred the doors with chairs after turning the locks on the knobs. Akane and Kouta also closed and locked the windows like they did on the first floor as they all heard heavy footsteps coming up the stairs. After locking every available entrance to the room, the orphans huddled together in the center with Mika, Yuu, and Akane doing their best to calm and hush the younger kids in the hopes that their pursuers would not hear them and leave. *3*
Unfortunately, they had no such luck.
The orphans cried out in fear when they saw the doors they had painstakingly locked easily kicked open as if they were made of card board and a tall man clad in a black cloak entered the room. Mika was about to order everyone to get out through the glass door to the balcony leading to another part of the building when it suddenly shattered and another man in a black cloak stepped inside, blocking their path to that exit as well. Now that all paths of escape have been closed off, the orphans were trapped with nowhere to go and even Mika had no idea what to do this time.
The orphans looked at their pursuers, who had found them so easily, in fear. This was it, they were going to be slaughtered right here like animals and prepared themselves to die when they noticed that the men, who looked deathly pale and had eyes the color of rubies, made no move to attack. After a moment of awkward silence and confusion, the cloaked man who kicked down the main door to the room spoke, his voice sounding mono-toned and devoid of any emotion.
"We have found you. You are to come with us if you want to live."
As simple as the words were, the orphans knew they weren't being given a choice in the matter and Mika did not even want to think about what might happen if they refused or attempted to resist. And so, he quietly told Yuu and the others to comply with their captors' demand.
"Everyone, just do what they want and we'll be okay!" Mika assured. Yuu, however, could still hear the unsaid "I hope" in his words.
Without another word, the cloaked man in front of them stepped aside and made a gesture for the orphans to get up and start walking back downstairs whence they came. The other cloaked man stood in front of the door to the balcony in case any of orphans attempted to make a run for it but none of them dared.
After being "escorted" out of the building where they had attempted to hide, the orphans found themselves, as well as groups of other children the cloaked people have managed to collect throughout the city, being loaded onto trucks like cattle. As soon as they were all locked in, they felt the vehicles start to move. Without any windows, the orphans had no way of seeing where they were being taken. Not that it mattered because life as they knew it was already over and would never be the same again…
SSSSSS
Sanguinem, sometime in 2015
Yuichiro Hyakuya slowly opened her eyes and took in a breath, holding it as she placed her hands on her chest and stomach. She had been trying to fall asleep for last hour but found that she could not due to the unpleasant and somewhat painful cramping in her abdomen. Looking around, she could tell that Akane and the others have already fallen asleep.
Ever since the small family who became known as the Hyakuya orphans were taken to an underground city called Sanguinem, they had lived together in this old, run-down house. They later learned that the cloaked people who captured them back on the surface world were actually blood-sucking monsters called vampires, creatures that were only supposed to exist in ancient myth and legend according to what their parents and teachers once told them.
Apparently, they were wrong for these creatures were very real and now ran every aspect of the lives of their human "livestock" or so the surviving children of the surface world were called. Even though they were not required to do any slave labor, only "donate" blood, the livestock children were slaves to their vampire overlords nonetheless for they were not allowed to leave Sanguinem. They were also given a curfew that they must obey every night under the threat of punishment. However, the children were allowed to roam the city freely when not at the facilities where their blood was harvested as food for the vampires. As long as they obeyed the vampire guards who came to their home to "escort" them to the blood-farming facilities when it was time for them to "donate", which was at least two to three times a week, the children were free to do as they pleased except escape. They were clothed, fed, sheltered, and given basic medical care when needed though it was only enough to keep them healthy so that the vampires don't end up harvesting contaminated blood from sick livestock children.
Time passed and the children's memories of the surface world started to fade as they became used to their new living situation. Not like they had any choice for there was likely nothing left for them outside the city now that their parents and other adult kin were gone. If left to their own devices after the apocalypse, many, if not all of the children, would have most likely perished either from starvation or illness stemming from the lack of medical care and sanitary living conditions. So in a way, the vampires did save their lives and thought their livestock should be grateful that they were being permitted to live at least somewhat freely in exchange for their blood.
Yuichiro, however, didn't exactly see it that way. If given a choice, she would have rather taken her chances on the surface then live in this cold, bleak underground city where nobody could tell day from night and didn't even have TV and internet as a window to the outside world. Days soon became weeks, weeks became months, and months easily became years. Yuu couldn't tell how long she, Mika, and the other Hyakuya orphans have been living in Sanguinem now since it was so easy to lose track of time when they could not even see the sun rise and set or the moon and stars come out at night in the sky.
But if she had to guess, the disguised girl would say that they have been living in the underground city for at least two to three years and that she should be about eleven years old by now. And although she knew when her birthday was supposed to be, Yuichiro could no longer tell when it came and went since she had no calendars to keep track of the days, weeks, and months. But that could also be said of any child in Sanguinem.
However, life in the underground city had not been all bad. Although the run-down house they lived in now was not nearly as comfortable as the orphanage or homes they once lived with their parents, it was still livable and far better than living on the streets. The home of the Hyakuya orphans was two stories with a kitchen and large living room as well as two bathrooms with decent-sized shower stalls. The kitchen also had a working stove and dinner table large enough for all the kids to eat on. However, the house did lack beds and other furniture so they made do by spreading futons with blankets on the floor in the middle of the living room, often sleeping close to each other for warmth. *4*
Now that their elderly caretaker was gone (as well as every human adult they knew of) the orphans depended on each other for comfort and survival. And ironically, their grim living situation had brought them even closer together than they were previously. As the second eldest, Yuichiro found herself the unwitting guardian of the younger kids next to Mikaela. And because everyone thought she was actually a boy, they looked to Yuu as another protector and provider while looking to Akane, the oldest female, as more of a nurturing mother who took care of things inside the house. *5* Even so, Yuu and Mika still tried to help out with housework as much as possible.
Right now, the other Hyakuya orphans were asleep with Yuichiro huddled next to Akane. The younger girl subconsciously had an arm draped across Yuu's chest and though it did not bother her, she was dismayed to find that she still could not fall asleep due to the uncomfortable cramping she was experiencing now. Perhaps what she needed was a hot shower and hoping that would relieve her discomfort, Yuichiro gently pried her orphanage sister's arm from her chest, got up, and went to the bathroom, making sure to walk as quietly as she could so that she wouldn't wake the others. As usual, Mikaela was not with them. In the last year, Yuichiro had noticed her brother going out, usually past curfew, and often coming home in the middle of the night before the other orphans even noticed he was gone.
And although curious, Yuu did not want to pry or invade Mika's privacy by asking him where he went as long as he came home safe every night. The blond boy insisted that he was perfectly fine and always took extra care to make sure he was not spotted by the vampire guards who patrolled the city at night.
Although she preferred that Mika not go out so late alone, Yuu had no choice but to have faith in her orphanage brother *6* and trust that he was able to take care of himself. Right now, she had a more urgent matter to attend to. As soon as the girl was inside the bathroom, she turned on the light and started to strip.
Like all the livestock children, Yuu wore a simple white uniform that slightly resembled hospital scrubs as well as a choker with an identification tag that all the livestock children were required to wear. However, unlike the other girls, whose livestock uniform resembled a dress, Yuu wore the boy's uniform which was a two-piece outfit consisting of a hooded, short-sleeved shirt and capri pants. Even though her parents were gone and she no longer had to pretend or dress as a boy, Yuu continued to do so from force of habit.
Upon their arrival in Sanguinem three years ago, all livestock children were given medical examinations to ensure that they were healthy enough to "donate" blood. And when the vampire doctor who examined Yuichiro discovered that she was really a girl, his brow rose, but he did not argue when Yuu insisted on wearing the male livestock uniform and keeping her hair short; his only job was to make sure the livestock were healthy, nothing more. The other vampires wouldn't have cared one way or the other; she could walk around naked and they wouldn't think of her as anything but a blood bag on legs.
After she had finished removing her clothes and hung them on the towel rack, Yuichiro turned on the water and waited for it to reach a comfortable temperature before stepping under the shower head, wetting her hair and reaching for a bar of soap. Unlike many of the other livestock children, who would often go for days or even weeks without bathing, Yuu was somewhat of a neat-freak because her parents have ingrained the importance of cleanliness inside her head since the day she was old enough to bathe herself.
And although she might not have agreed with everything they taught her, Yuu did agree with them on being clean and often enforced that on the younger kids in her household as well (with Mika and Akane's help, of course). But unlike Mika, who would often help the younger boys shower and scrub their backs while Akane did the same with the younger girls, Yuu always insisted on showering alone and often late at night or early morning when everyone else was still in bed.
As Yuichiro tried massaging her abdomen to relieve her uncomfortable cramping, she noticed a wetness between her legs that was not from the shower. Looking down, the young girl gasped in horror when she saw what looked like blood dripping down her inner thighs.
Oh, my god! What's happening to me?! Yuu thought frantically as she slapped her hand over her mouth to keep herself from screaming in terror and waking the others. What could possibly be wrong with her since she felt perfectly fine until she noticed the cramping in her abdomen earlier? Could this bleeding mean that she was sick or dying? *7*
Yuu desperately wished someone would answer her but since there was no one, she slid to the floor of the shower stall and found herself sobbing uncontrollably. Although she tried to be quiet, Yuu's crying did not go unnoticed by Akane, who had just woken up moments ago to use the restroom. Concerned, she started rapping softly on the door.
"Yuu? Is something wrong?" she asked.
Realizing that she had woken Akane up, Yuu panicked and tried to think of something to get her sister to leave.
"I'm fine, Akane! I'll be out in a few so just go back to sleep!"
Although the younger girl knew that she could just use the other restroom, Akane felt that something was not right and hesitated to leave.
"Are you sure, Yuu?"
"Yes, I'm sure!"
Although her orphanage "brother" tried to sound reassuring, Akane was not convinced.
"Yuu, you're scaring me, please open the door!" she pleaded.
Despite knowing that the younger girl was only concerned for her, Yuichiro grew angry.
"I'm fine!" she shot back, a little more harshly than she intended.
As soon as she heard Yuu's angry and fearful tone, Akane knew for certain something was wrong and could not bring herself to leave. After waiting for another five minutes or so, she thought about trying to persuade Yuu to come out again when she heard the front door to their house being unlocked and opened. Knowing that it could be none other than Mikaela, Akane quickly rushed downstairs to meet him. As soon as he saw the expression on her face, Mika asked:
"What's wrong, Akane?"
Looking around as though making sure none of the other kids were awake and listening, Akane pulled Mika closer to her and said in a low voice:
"It's Yuichiro! I heard him crying in the shower and he won't come out!"
"Really? What's wrong with him?"
"I don't know but he's been in there too long and I'm worried about him. What if he's hurt?!"
"Ok, then we'll have to make him come out. I don't want to invade his privacy but this is for his own good" Mika answered as he rushed upstairs after gesturing for Akane to follow him. As soon as they were in front of the bathroom door, Mika rapped on it just loud enough to get Yuu's attention while hoping that the sound wouldn't wake the other kids.
"Yuu-chan? It's me, Mika! You need to come out, Akane says you've been in there too long and it's not good for you!"
"I'm fine, Mika! Please leave me alone, I'll be right out in a few!"
As soon as he heard that, Mika turned to Akane who shook her head.
"Don't listen to him, that's what he said over five minutes ago. If he's hurt and we don't get him out, it might be too late to help him!" she hissed.
Mika sighed and nodded. He hated himself for what he was about to do but there was no other option; he simply would not risk Yuu's well-being and that took priority over her current desires. Taking his key ring out of his pocket which also had the key to both bathrooms as well as the front door, Mika stuck it in the keyhole, unlocking the door before turning the knob. Akane stood next to him, not knowing what to expect. What they saw when Mika finally got the door opened was just as shocking as when they witnessed the apocalypse on the surface world three years ago.
Yuichiro Hyakuya, their orphanage brother of three years, was really… a sister!
At first, Mikaela and Akane Hyakuya thought that their minds were playing tricks on them but when they blinked and looked again at Yuichiro (who was completely naked in the shower stall with a see-through glass door) there was no mistaking the feminine curves of her waist and hips, not to mention the lack of a certain something between her legs that would have been there if she was indeed a boy. Mikaela gulped as his eyes wandered off to her chest where he can see the protuberance indicating her br-
Before the blond boy could even complete the thought, Yuichiro blushed furiously in embarrassment, not only from having her true sex revealed, but also by being seen totally nude by a boy, a real one, and for the first time in her life.
"Stop staring!" she squealed as she crossed her arms over her developing breasts proactively. So embarrassed was Yuichiro that she completely forgot about the blood dripping onto the floor of the shower stall from between her legs. If she didn't die from that, she probably would from embarrassment.
As soon as Akane recovered from her momentary shock, she quickly ordered Mikaela to cover his eyes while she grabbed a towel from the rack. As she approached Yuu, she noticed the blood and finally understood what made the older girl so upset.
Yuichiro was having her first menstrual period.
"Yuichiro…its ok" Akane began gently as she opened the door to the shower stall. "You have nothing to worry about. This bleeding…it's normal for all girls."
Girl. Now that it's actually been said, Yuu (and Mika) couldn't hide from reality any longer. Everything finally started to make sense to the blond boy now. Especially why Yuu had always refused to undress in front of anyone or shower with him and the other boys despite Mika's begging as well as why she always insisted on showering alone and at odd hours of the morning or night. *8* Although Mikaela did have nagging suspicions in the past, he simply brushed them off as Yuu just being very shy about disrobing in front of others.
After she had calmed down somewhat, Yuu looked at Akane in confusion as she allowed the other girl to turn off the water and begin to dry her with the towel.
"What do you mean?" she asked.
"Your mom never told you?"
"Never told me what?"
"That all girls bleed like this once a month. It's called a 'period'."
"You mean I'm not going to die from it?"
Akane was startled at her sister's statement and wondered why Yuu would think that when it finally occurred to her that the older girl's parents might not have told her that menstruating was a normal function of the female body, especially if they wanted her to be a boy. But she obviously wasn't and Akane felt that she was obligated to tell Yuu the truth in their place.
"Of course not! All girls go through this every month for a few days! I just started to last year."
"Really? And how much longer will I have this 'period'?"
"Oh, like about another thirty to forty years."
"What!?"
"My mom used to tell me that it's important for every girl to have a period since it cleans out toxins in the body. You would actually die or be very sick if you didn't have one."
"Buy how? Why?"
"I'm not sure; that's all I've been told. Anyway, we need to get you cleaned up. I have some extra tampons you can wear in your panties so that you won't bleed inside your pants." Now that she finally had an excuse to get Mika to leave so that she could finish drying Yuu, Akane said: "Mika, go into the box I keep under the kitchen sink and get me one. It's a soft pad wrapped in plastic."
Blushing that Akane would make such a request of him, Mika almost wanted to refuse but forced himself to comply since he knew it was what Yuu needed now. Turning, the blond boy left the bathroom and made his way to the kitchen without another word.
Later that night, after Akane had helped her dry off and gave her what was called a "tampon" as well as an explanation for what she had just experienced, Yuichiro Hyakuya was able to sleep much easier. But not before swearing her eldest orphanage brother and sister to secrecy about her true sex because she was not ready for everyone to know just yet and may not be for a while.
Mikaela had no problem making that promise. For even now, he still couldn't believe it. And might not for a while.
And possibly, a long while.
Footnotes
1. In the LNs, Mahiru tells Krul exactly where to find the Hyakuya orphans and they were her primary objective when the virus struck. The difference between my AU and the anime version of this scene is that instead of running to the orphanage, the kids leave it which would likely end up putting Krul on a wild goose chase. But I think this possible since things don't always work out as planned in life. Once she realizes this, Krul merely orders her vampires to collect all the children in the city and bring them to Sanguinem where the Hyakuya orphans can be sorted out later.
2. To be clear, the virus was spread by humans, not the vampires. I merely used the dialog in the English dub of the anime regarding the announcement of the virus in the opening. It was a bit difficult for me to hear so I had to strain my ears while turning up the volume in my computer but I hope I got it somewhat right.
3. In the canon story, there are about 14 kids total in the Hyakuya orphanage but only Yuu, Mika, Akane, Kouta, Chihiro, Taichi, Aiko, and Fumie were specifically named. To make things a bit easier for my AU, only those eight will consist of the Hyakuya orphanage kids.
4. In the manga, the home of the Hyakuya children in Sanguinem is very spartan in comparison to the anime. It consisted only of a flat with a bare floor and no furniture. I have decided to make their home closer to its more luxurious anime counterpart with two stories, a kitchen, two bathrooms, etc. But no beds so they have to sleep on the floor together.
5. In canon, Yuu is the second eldest male child so he *gets* the responsibility of being a protector and provider for the younger kids while Akane is more nurturing like a mother. It was also unsafe for young girls to go out alone in Sanguinem so Mika and Yuu kept her at home most of the time. In my AU, everyone thinks Yuu is male so she gets the same role as male!Yuu and will continue to play it even after Mika and Akane discovers her secret because she doesn't want anyone to know she's really female.
6. In the canon story, the Hyakuya orphans refer to themselves as 'family', not 'brothers and sisters', especially Yuu and Mika. I think this was deliberate on the part of the producers to cater to the Mika/Yuu shippers. In my AU, I prefer to refer to the kids as brothers and sisters.
7. Because she did not go to school for very long before the apocalypse struck and her parents never talked to her about it, fem!Yuu did not realize that menstruating is normal for all women of childbearing age and is naturally frightened when she finally experiences her first menstrual period. The average age of menarche is about 11 but some girls can start as early as 8 or late as 16 years of age. In my AU, Akane started menstruating at 9 and her mother did tell her about it so she was able to explain to fem!Yuu that she has nothing to worry about and that having her period is normal.
8. Mika actually did suspect the possibility of Yuu being a girl when they first wrestled on the floor of the orphanage and he noticed her body felt different as well as her unwillingness to undress in front of others. But he has been brushing them off as Yuu just being very shy for years until seeing her naked confirmed her sex. He also thought her body feeling different was just his imagination. It could happen; we're talking about kids here ;)
