Mokou decided she would visit her troubled friend. She saw Keine with her head in her arms on the top of her desk. This prompted her to run in and see what was going on.
"Don't cry, Keine!" Mokou called out, pushing the sliding door open and rushing into the desolate classroom.
"I'm not crying..." Keine replied. "I just have a killer headache."
"Do you want me to go to Yagoukoro and get you some Advil?" Mokou asked, putting a hand on Keine's shoulder.
"I have some pills." Keine said, raising a hand slightly. "There is no need."
"This always happens," Mokou replied. "the day after a full moon, you get a severe headache."
"It's not from 'caving' people." Keine replied, a tone of sarcasm.
Mokou chuckled. "Oh, yeah! I forgot about those rumours!"
As Mokou laughed, Keine looked stern.
"Uh... sorry." Mokou contained herself at Keine's upset.
"It's okay for you to joke..." Keine said calmly. "after all, you're not the one who loses control of herself at the full moon."
"You never used to do that!" Mokou exclaimed. "What the hell happened?"
"You think I know any better than you do?!" Keine asked, frustrated.
"Well, you know that Satori did it." Mokou announced.
"No, actually." Keine stated. "That was a decoy. To-to give myself some time to come up with a solution to this problem without being stabbed to death by pitchforks and burned with torches."
"That sounds very European." Mokou replied.
"Meh." Keine shrugged. "I've seen it happen here in the East too."
"Where do you think they got the 'Angry Mob' idea from?" Mokou asked rhetorically.
"...Why are we even talking about this...?" Keine was confused.
"Because you said-"
"Never mind! Mokou, what do you have in mind?"
"Ramen. Teriyaki. Suki-"
"BE SERIOUS FOR ONCE IN YOUR LIFE!" Keine slammed her fist down on her desk angrily. "STOP PLAYING GAMES WITH ME!"
Mokou flinched. "Keine! This isn't like you!"
"I-I know..." Keine took a breather. "I'm so sorry."
Mokou took a sigh of relief. "I thought you were gonna chew my head off just now."
"Do you have to joke about Watanabe's mother like that?" Keine complained.
"Wait, you-"
"Yes. I chewed her head off." Keine said, shamefully. "Happy?"
"No..."
"It's all because you didn't kill me, you know." Keine pointed out.
"I can't, Keine!" Mokou snapped back. "I'm your best friend! I can't do that to you! I-it's bad enough you already have a short lifespan! I don't wanna cut it shorter!"
"Hakutaku are normally human-friendly..." Keine began. "But for some reason, I'm just getting angrier and angrier, and I'm losing control. I have a need to-to destroy..."
"Destroy?"
"Destroy."
Mokou, who was pacing back and forth, stopped dead in her tracks. "You feel like destroying things?"
"Destroying everything." Keine stated, a callous and murderous tone overcoming her usual calm, collected voice. "People. Youkai. Objects. It doesn't matter. Perhaps the Hakutaku is tired of everything? Tired of the millions of disasters it has to remember and keep track of... tired of the millions of people born and dying every day..."
"Keine..." Mokou reached out to her.
"Tired of people cheating time..." She whipped her head and looked at Mokou. "Tired of immortals! Tired of Youkai! Tired of the human race!"
Mokou began to feel uncomfortable. She knew deep down, that Keine's special ability to conceal history could change her life forever. She knew that Keine could negate her ever drinking the Hourai Elixir in the first place, or she could, in Hakutaku form, make a history where Mokou's Immortality gets negated by a new potion Eirin brews. Mokou would prefer to keep her distance at this point.
"Tired of Gensokyo..." Keine said, placing her hands on the sides of her face, worried.
Mokou walked close to her distressed friend and hugged her. "Keine, we'll work this out, I promise."
"Mokou, I'm scared." Keine spouted out. "What if-when the Were-hakutaku destroys everything..."
"...It destroys you as well?" Mokou finished Keine's suspicion. "And then itself?"
"Perhaps it wants everything to cease existence." Keine pondered. "I-it's just how I feel..."
"See?" Mokou stated. "You can still have independant thought, at least. You figured all that out by yourself!"
"Yes." Keine stood back up and walked towards her window and gazed out. "But for how long?"
"Tonight's a blue moon, lucky us." Mokou stood beside her. "That means Hakutaku again tonight."
"Not if I stay away from the moonlight." Keine replied.
"So, you'll spend the night in the basement?" Mokou asked.
"Yes."
"Bummer." Mokou said. "I really wish Kaguya could meet the 'new' Hakutaku."
"I will not recklessly endanger everyone for the sake of your entertainment." Keine stated, annoyed.
"Damn it." Mokou hung her head down. "Well, it was worth a try."
Mokou walked to the door. "Oh, and by the way. Koishi told me to tell you that you had better take down those posters you hung p all over town."
"I will." Keine said, raising a hand. "I promise."
"Okay, see ya!" Mokou waved.
Keine waved back and then bowed.
