Outside of Eientei, Yorihime and Eirin were training with each other, as Toyohime watched while smiling on the ground. They both seemed in the middle of the heat of the battle, as Yorihime constantly attempted to close the gap between the two whilst Eirin simply dodged away, successfully keeping Yorihime away from her and at a distance. "Try and find an easier way to close the gap between you and your opponent, Yorihime," Eirin said, firing an arrow with impressive accuracy considering the bullets that were all over both of their vision, forcing Yorihime to move to the side and almost get hit directly by another of Eirin's bullets. "If you keep getting forced back, find a new, inventive way to get through. Remember, no using your powers just yet. Getting used to fighting without them will, in turn, increase your abilities with them."

"Right," Yorihime nodded, looking around as she weaved in and out of different bullets, before flying through an opening to get behind Eirin. She found a way through the bullets, approaching Eirin's back as she turned around, firing a bullet with incredible accuracy to halt Yorihime in her tracks. However, Yorihime smiled to herself as her sword connected with it, launching it off in the distance and allowing her to reach Eirin, swinging her sword down as the Lunarian Sage raised her bow to block it.

"Well done," Eirin said, using her free hand to load her bow with and arrow, facing it directly towards Yorihime's chest as she quickly backed away, moving to dodge the arrow. However, she found herself being forced down towards the ground by Eirin's attacks as she moved above Yorihime. When the sister's feet hit the ground, spirits began to circle her, before locking her in and trapping her on the ground as the fire stopped.

"Astronomical Entombing," Eirin said, as Yorihime was locked in a small space with no immediate way out. Reisen hopped over and landed next to Toyohime, to which Toyohime took note of her presence, turning around to smile at her.

"Hey, Reisen," Toyohime said, before her eyes looked over to the cage that surrounded Yorihime. "We're training with Lady Yagokoro right now. She might let you join in, after all, it is an important scenario that is coming up."

"Oh, i've already asked Master Kaguya if she would help me," Reisen said, looking over to the fight as well. "I… I thought the three of you would be too busy training together, and that Kaguya was free."

"Oh, I see," Toyohime said, holding her fan over her mouth. "That's fine then."

Eirin shot out a large bullet, connecting with parts of the cage which released more bullets outwards, as well as into the enclosed space that Yorihime had to dodge through. Eventually, as more bullets from the cage Yorihime found herself surrounded on all sides, with no immediate escape from the barrage of bullets that connected with her. She also couldn't find herself the ability to move to destroy the spirits with her sword, forcing her to raise her left hand to face the left side of the cage. She released a stream of bullets towards that side, which destroyed the spirits, creating an opening for her escape. As well as this, it stopped the bullets coming from those spirits, which allowed her to quickly fly out of the cage and up towards Eirin, who cancelled the spell and raised her hand to stop Yorihime in her tracks. Yorihime stopped in the middle of the air, a little beaten up from the Astronomical Entombment spell.

"It appears you started to easily absorb the concept of danmaku at the end there," Eirin said, with a smile on her face. "Back on the moon, you had no need to learn how to use danmaku attacks as your sword skills and ability were enough to pull you through. However, the more abilities of attack you learn, the better a fighter you will become. Especially with this oncoming threat, going from simple danmaku as you used there to more complex danmaku patterns will be beneficial against stronger opponents. That's enough for you right now, so you can learn how to use danmaku more effectively along with sword skills in your spare time."

"Yes, Lady Yagokoro," Yorihime nodded, floating back down towards the ground. Eirin's eyes darted towards Toyohime.

"Now, Toyohime. It's you tur-" She said, as Toyohime perked up and bit her lip slightly. However, she was cut off by Kaguya's entrance. "Lady Kaguya, i'm sorry if we woke you."

"Must you be so noisy so early in the morning…" Kaguya said, rubbing her eyes as the tone of her voice showed she had recently woke up.

"Lady Kaguya, it's three o'clock in the afternoon," Eirin said, sighing.

"Ah, I see…" Kaguya said, before yawning. "I'll go get ready for the day… Eirin, you have a customer."

"Ah," Eirin said, as her face turned to one of surprise. "My apologies, girls, I should go tend to this," she said as she flew back down to Eientei. Toyohime sighed in relief as Eirin went away.

"Looks like I got lucky, huh?" Toyohime said to Yorihime, who was still stretching off her fight with Eirin. "No danmaku training for me! Now i'll get to focus on the parts I am good at."

"Toyohime…" Yorihime said, narrowing her eyes at her sister. "You'll find it hard to beat that martian person if you don't learn new ways to attack them."

"Well, I guess you're right," Toyohime said, before smiling. "But knowing my luck, next time I won't get her as my opponent. Then i'll be able to beat whoever I go up against." after she said this, Yorihime sighed at her sister's egotistical attitude as she noticed Kaguya walk over to Reisen.

"Come on, Reisen… you have to train hard with me as well…" the Lunarian Princess said, yawning as Reisen nodded.

"Yes, master Kaguya," She said, walking away with Kaguya after waving a happy goodbye to the sisters. It had appeared she had began to get used to having them around also.

Eirin came into Eientei and stood behind the counter, looking around at the store. 'Lady Kaguya said I had a customer but… they must have already left after the wait,' She thought, before sitting down at the counter. 'In case anyone else comes, i'd best look out here. I'm sure the two of them will do training on their own for the time being.'

"Boo!" Kogasa said, leaping up from behind the counter in an attempt to surprise Eirin, who gave a questioning gaze at the umbrella youkai.

"Ah? I don't recall seeing you here before. Why were you hiding there?" Eirin asked Kogasa, who quickly turned to a disappointed face.

"Auu, every time I meet a new person they're never surprised by me…" Kogasa said, as she slumped against the desk in a defeated manner. "I guess yesterday must have been a lucky break… Marisa even said if I could surprise that person then it would only be because of luck…"

"Marisa's words are really not something to latch onto…" Eirin sighed, scratching her head a little in confusion about Kogasa's nature. "Although… if it's what you're looking for, it did surprise me to have a customer today of all days, especially with what seems to be on the horizon."

"Eh? Really!?" Kogasa asked, as her face brightened up again. "Yay! I surprised a really strong person today! I'll stay full for a long time now!"

"Ah - ha, I see…" Eirin said, still confused about Kogasa's nature. "Anyway, what is it that you came for, again?"

"Oh, yes," Kogasa said, scrambling to remember why she came to Eientei in the first place. "Let's see… oh, yes! Do you have a medicine that let's someone see an object for exactly what it is, no matter what? Oh, and we need it in high quantities!"

"What's this about?" Eirin said, puzzled as to the order she was given as well.

"Well… my friend has the ability to make objects unidentifiable, and Miss Yukari tasked her with making Gensokyo unidentifiable from the Martians," Kogasa said. "She couldn't make the whole of Gensokyo turn that way, but she figured that if she went around and turned every single tree and house unidentifiable then when they invade, they'll have no idea what everything is and be confused! Then, afterwards, we'd be able to exploit their confusion and surprise attack them, easily winning!"

"Hm, that plan does seem helpful," Eirin nodded, as she thought about what she could do. "You need this drug for everybody in Gensokyo to make sure they still see Gensokyo for what it is. That's a tall order. Can I have a demonstration of how this ability works, please?"

"O-oh, okay!" Kogasa said, cheerfully walking out the door and calling Nue to come inside, before walking back in with Nue's floating orb next to her. "This is my friend, she prefers staying like that rather than using her real form. So, we need an object for you to test."

Eirin nodded, reaching beneath the counter and bringing out a glass, before placing it on the table. "Is there anything else?"

"I don't think so," Kogasa smiled, as Nue sighed through her orb form.

"Kogasa, everything becomes unidentifiable because everyone sees it as a different object," Nue said, floating around a little. "So, both of you will see it as something different. I'd assume that would be important information."

"Oh- I forgot," Kogasa sighed, twirling her umbrella slightly as Nue used her powers on the glass, making it unidentifiable.

"I see a fuzzy mess of lines…" Kogasa said, to which Eirin shook her head in disagreement.

"I see some sort of static like arrangement," Eirin said, before reaching out to grab it. She felt the glass as a normal glass, rather than whatever it had been made to look like. "Ah, so it is only unidentified to the eye, not to the touch," she said. "This shouldn't be too difficult. It's just a simple case of making a drug that affects people's eyesight. Although, with the drugs affects, you won't be able to conceal yourself from anyone either."

"I thought about that…" Nue said with a sigh in her voice. "I'll just stay really high in the air and hide around to make sure nobody sees me. So, we'll need about two hundred, just to be on the safe side. I've heard someone called Keine can conceal the human village, so we don't need to account for those humans."

"Indeed," Eirin nodded, as she got to work behind the counter. "Come back in about two hours, and I should have everything completed with how large the dose sizes should be. In that time, you can tell everyone about what is happening."

"Right!" Kogasa said, twirling around as she walked out of Eientei.

"Thank you, Miss Yagokoro," Nue said, as she also floated out of the door, leaving Eirin alone to work out her new drug in development would function.

Outside of Eientei, Nue stopped, causing Kogasa to stop also and look around at her. "Kogasa, you go around the place telling everyone about the plan. I'll go to the Human Village to meet this 'Keine' person and have her use whatever her power is to keep the human village safe."

"Oh, right!" Kogasa said, smiling as she slowly hovered away. "There'll be lots of people to surprise out there! Thanks, Nue!" She said, flying off towards the Forest of Magic.

As Kogasa flew off, Alice walked through the bamboo forest and towards Eientei, looking up as the glowing ball flew away. She sighed, as she opened the door. Eirin immediately perked up from her job.

"Ah, another customer. Appears we're busier than I expected today," Eirin said, as Alice nodded, taking a seat at the counter.

"I'm just here to get some more gunpowder for my dolls," Alice said, as she showed a doll that appeared completed to Eirin, however had a slight opening for gunpowder to be put into. "I ran out while preparing extra, backup dolls for the invasion. Marisa's been bugging me to train with her as well, so the earlier I have this job done, the earlier I can practice my skills against her."

"Ah, I see," Eirin said, standing up to look for gunpowder. "I just had two other visitors, in fact. One of them had the power to make objects unidentifiable, so she's planning to do that to all the trees, houses and shrines in Gensokyo. I'm creating a new drug for everyone that will have their eyes be unaffected, so they see Gensokyo normally whereas the Martian's do not."

"Ah, that would be Nue, most likely with Kogasa," Alice said, placing her doll on the counter. "Marisa told me about them."

"I did hear the name Kogasa," Eirin said, as she took some gunpowder out of a cabinet. "It's a pretty good idea, to give them credit. When they arrive here, they should be confused as to what everything is, letting us take the upper hand."

"It does seem that way," Alice said, nodding. "And with everyone preparing, it seems there's a high likelihood of us winning, unless the Martian's are truly that powerful. Even Yuuka Kazami is getting ready now. She heard from someone that Marisa was telling people about it, so she came asking what it was about. She said it's a perfect opportunity to test some 'Ultimate Magic' she was talking about. I have no idea what it is."

"I see," Eirin said, putting a rather large container of Gunpowder on the counter for Alice. "Yuuka is one of the most powerful youkai, i've heard. I must only assume the 'Ultimate Magic' is much stronger than many of the other things we could hit them with. Anyway, here you go. I gave you some extra this time given the circumstances."

"Thank you, Eirin," Alice said, taking the gunpowder as she stood up from her seat. "Good luck preparing for the invasion. If they beat Lunarian's like you, then i'd still rather you watch out."

"Good luck to you also," Eirin said, as Alice left Eientei. Afterwards, she got back to work preparing the drug for Nue and Kogasa.

(Author's Note: No 'Spell Card' thing at the end this time as no new characters were introduced, and I don't have anything to say about the Martian city at this current moment (It is late at night when i'm writing this, though.))
