This took a while to write since I was procrastinating and working on other stuff, but it's out now. Anyways, Jewel Joker 6 was pretty awesome! It's a Guardian reunion! And Saburo will be reuniting with the Guardians here too, so let's get on with it! Minna no Kokoro: UNLOCK!

Saburo looked at CHU lying down on a bed in the nurse's office, where all the other victims of this mysterious heart egg stealer. How could he have let this happen? One of his fellow guardians has fallen victim to the mysterious thief, and it was all his fault. He should've never left CHU alone like that.

"Oh dear. What am I going to do? How am I going to explain this to the others!"

Saburo looked back at CHU. He needed to catch whoever was doing this fast.

"Don't worry, CHU. I'll save you."

His mind drifted off to CHU's mother. Why didn't she like talking about her? It's probably best to leave that question until she wakes up.

As he walked out of the nurse's office, he noticed a mirror lying on Lucia's bedside table. He had a mission to do, but he couldn't help but look at his reflection. Saburo liked mirrors. Why? It's because he could confirm that he is still here today through them. He always had a faint presence, and every day, he worried about disappearing into nothingness, with not even his sister remembering that he existed.

Saburo never thought he could amount to anything in his life. His sister sparkled and was very popular with people her age, and the rest of the Guardians outshone him. But now, being the only Guardian in the Academy, this was his chance to finally prove himself. That Saburo Imai isn't just a useless nobody. That even without a Heart's Egg, he deserved his spot in the guardians.

With a newfound sense of determination, Saburo grabbed the mirror, whispering "Do you mind if I borrow this, Nanami-san?", and ran out of the nurse's office.

Saburo stared at both Yaya's notebook, and of the transcript of Otto's court trial that he wrote. Between the various doodles Yaya has drawn and information that Saburo already knew, tbere wasn't much he could go off of.

"Oh dear. How am I supposed to figure this out?"

That was when he remembered that Tsukasa was the one who told Yaya the list of suspects. Since there had been two more cases since the court case, that means that he can narrow it down even more! Probably… Alright! It's time to ask Tsukasa. Wherever he might be.

Saburo knocked onto the door to the Chairman's room. Said Chairman opened it.

"Saburo. What brings you here?"

"I need you to look at the tracking data footage again."

Tsukasa smiled, as he gave him a sticky note. "I'm one step ahead of you."

Saburo looked at the sticky note. It looked like Tsukasa managed to narrow it down to two people.

"Though I think you might need to watch your back."

That was when Saburo noticed one of the suspects, Sayaka Miki, standing right behind him.

"Uh, hey. Sayaka-chan."

"Oh, hello. I was just looking for the nurses office."

"Miki-san. You've been a student here for, how many years? Two?"

"Three, actually." Sayaka made an innocent grin.

"That doesn't matter. You should know your way by now"

Saburo offered to ask. "Why are you looking for the nurse's office?"

"Mami's a close friend of mine, you know."

"Oh, I see." Saburo looked at the sticky note in his hand. He can't just straight up accuse her of being the culprit then and there. And besides, there was one other culprit that he needed to investigate.

"I need to go now. There's something I really need to do."

Tsukasa also spoke up. "I also need to get back to my duties. See you, Miki-san."

Sayaka watched as Saburo and Tsukasa parted ways. Octavia flew up next to her.

"I think they're onto us. Should we go follow that boy?"

Sayaka nodded. "Even if he doesn't have a Heart Egg, we can't let him get away with revealing us. And I think he could be really useful for us."

Saburo spotted the last suspect, Misaki Watarai, listening to Kaoru Seta's Shakespeare recital. He walked over to her.

"Misaki, may I talk with you for a second? In private, please."

"Oh, of course!"

So the two of them went behind the school, around the place where Mami got her Heart Egg stolen.

"Do you recognise this place?"

"Huh? Why?"

"Are you friends with Kanon?"

"Yep! Of course!"

"And the robotics club?"

"Why are you asking me these questions." The realization struck her. "Wait! You don't think I'm the one stealing the Heart Eggs? I would never do such a thing to Kanon-chan! Or Kura-chan."

"Are you sure? Because the only other suspect is Sayaka, and she's friends with Mami, so turning on your own friend isn't out of the question. I just need you to answer a few more questions."

"Well make it quick. Kaoru's Shakespeare recital is ending soon"

Saburo picked up Yaya's notebook and started writing in it. "So, where were you yesterday at, I think… 4:28pm?"

"I was in the Home Ec room helping out with the cooking club."

"Do you know who else was with you-"

"Of course!"

As Misaki told her who was with her in the clubroom, Saburo noticed Octavia in the reflection of the mirror.

"Uh… I have to go to the bathroom! Sorry!"

Okay, Sayaka is definitely the culprit. Why has she been following him the entire day?

Saburo was sitting in a stall. He knew that Sayaka had the ability to enter the boy's bathroom anyways. He thought that she would need time to get her signal jammer. He needed to think of a plan quickly.

He heard a voice come from the neighbouring stall. "Saburo, you can't hide from me."

"Y… you can't steal my Heart Egg! I don't have one!"

"Oh, I know. But I can't have you tell any of your Guardian Friends. So I'm gonna cut you a deal. You shall not tell anyone that I'm the culprit, and you need to alert me if I'm about to get caught."

Saburo scoffed. "And what's in it for me?"

Sayaka giggled. "If you tell anyone, then I'll go down to Earth, and steal your sister's heart egg!"

Saburo gasped. There's no way she'd do that to Lisa!

"You can't do that! You- you don't even know where she lives!"

"Oh, do I? You could say that Octavia helped me do some not so legal snooping."

Saburo whimpered. Now Sayaka knows where he lived.

"Have you been targeting me all this time?"

"I have. I was actually planning on going for you first, but when I noticed CHU sulking in the girl's bathroom, I just couldn't pass up the opportunity! It got your attention, right?"

Saburo looked away.

"You tried to play the hero, you tried to finish this mystery once and for all, and yet, you are bound into a deal with me."

"I will not let you get away with this!"

"Oh, you will. Because even if you managed to get this far, in the end, you are too powerless to stop me. You are nobody."

Saburo looked into the mirror. His reflection looked ever so slightly fainter.

Sayaka heard a knocking on the door of her stall. She spoke to Saburo. "You better let that person in. We'll finish this conversation elsewhere."

So the two of them were in Saburo's room.

"So, first order of business. Give me your notebook."

"It's Yaya's notebook, you know."

"Whatever. Give me it!"

Saburo gave the notebook to her.

"Good boy."

Octavia flew up and inspected him. "He looks so pathetic, Sayaka. Like a wet dog."

Sayaka nodded.

"The Guardians will find out about it!"

"Will they? Because next up on my hitlist is the almighty Three's Chair"

Saburo gasped.

"You know there's nothing you can do about it, so be quiet. Anyways, second order of business. I want you to invite your sister up here."

"You can't make me!"

Sayaka grabbed Saburo's phone from his pocket. "Oh wow, you have no phone password. How secure." Then she looked through the contacts and dialed Lisa, then gave the phone to Saburo.

"Ah! Saburo! Nice to see you still keeping in contact. How's space been?"

"I… uh… well…"

"Give me that!" Sayaka snatched the phone from Saburo and took it. "Hey, Lisa, was it?"

"Who's this? Saburo, did you make a new friend?"

"Mhmm… Saburo was thinking that you should come to the Space Academy and meet me!"

"Ooh! Really?"

"Yeah. Tell the Guardians that you want to tag along!"

"I will~!"

"Wait! Onee-chan! Don't-" But it was too late. Sayaka already hung up the phone.

"Like I said, what are you gonna do about it? Now, you are gonna keep quiet to your friends or else your sister is going to get it. Do you understand?"

Saburo could do nothing else but nod.

"Good boy. Here, have a treat for being so obedient"

Sayaka threw him a candy bar and walked away.

A few days later, the seven Guardians finally returned to the Academy.

"Welcome back, Academy," Caren said.

"It's nice seeing this place again," Rui added.

"Eh, I don't really care." Ran said, "What I'm actually curious about is…" The eight of them all looked at their special guest.

"So this is Seiyo Space Academy. Looks stylish!"

"You'll be accompanying us until Tuesday, right?"

Lisa nodded.

They all walked in and met up with Saburo.

"Saburo! It's so good to see you!" Lisa ran over to Saburo and hugged him.

Tadase laughed. "Sounds like your sister is the affectionate type, Saburo,"

Hippo looked at him. "So… uh… "

Saburo gasped. "I… she… well…"

Saburo looked at his sister. He couldn't let her get into harm's way.

"It's best to see for yourself. Onee-chan, how about I take you to your room"

"I would love that! Oh, and you said someone wanted to meet me?"

"Uh… yeah. Right this way."

Saburo couldn't stop thinking about what Sayaka might do to his sister, to his friends.

As Saburo took Lisa to Sayaka, he looked at Tadase and whispered, "I'm sorry, Tadase"

Later at dinnertime, Rui and Hippo noticed that CHU was missing.

"Looks like Tamade-san decided to eat in her room again." Rui spoke.

"Wait, has anyone seen CHU-san lately?"

The two of them stopped and looked at each other.

"Don't tell me."

That was when Otto walked up to them.

"Otto-san, where's CHU?"

Otto looked away. "Well… you see."
