Seraph of the End: Red Scarlet

  Later, back at the base, Mitsuba slapped Yuichiro and Atsushi for being so reckless and stupid. While Atsushi apologizes with some regret, Yuichiro actually likes being beaten up by Mitsuba, and tells her to beat him whatever she wants. 

  "Eh?" Atsushi responded to this. "What are you?" 

Yuichiro then turned to him. "I don't care." 

After that, Shinoa reminded Yuichiro to be nice to Mitsuba since she has a dark past. 

Atsushi then understood that because he knows the plot very well in his previous life.

  Then, Mitsuba asked Atsushi when he will leave the Imperial Demon Army for the Red Scarlet Army. 

  "In the near future." Atsushi looked at his weapon with a mystery. 

  "What do you mean by that?" Shinoa asked back. " At just the right time," responded Atsushi. This surprises them. "Are you a mental?" 

  "Well, I think I would never see you guys again once I leave," Atsushi reasoned out in response, "so I'll stay for a while. That decision is deliberate and official for myself."

  Later, in the shower, Mitsuba rants how annoying and stupid Yuichiro is. Then, Shinoa abruptly enters in and said to her that she'll fall in love with Yuichiro first before her. She also suggested that she also hates him because he reminds her of her past behavior. Upon hearing that, Mitsuba looked at her. "W-What are you doing here?" 

But Shinoa didn't mind at all, and enters in without respecting her privacy. 

This scuffle-like attack really caught the boys' attention. 

  "No..." Atsushi responded. 

Then to his friends. "I'll be back." 

He then went to the girls' shower to check it out, but before entering, he covered his eyes with his right arm so he would not see the girls' nakedness. 

So, he did, and he stood at the doorway. 

  "What are you doing, Shinoa-chan?" he asked Shinoa directly. 

The two girls then looked at him. 

  "You pervert!" Mitsuba responded to this. 

  "How? I covered my eyes just for this," Atsushi replied. 

  "What are you doing here?" Shinoa asked. "You're a boy." 

  "No, what are you doing with Mitsuba-chan?" Atsushi asked back. "You're disturbing her privacy!" 

But Shinoa retorted, "Oh, nothing." 

  "What are you?" Atsushi asked. 

At this point, Mitsuba gets what Atsushi did to prevent himself from being a pervert. 

Atsushi then sighed in mild annoyance. "Sorry, I'm going now." 

He then went back to the boys.

  Upon arriving there, the girl gives out a tip that the vampires are at Omotesando Station raising human livestock. At that point, Atsushi removes his arm from his eyes. 

  "Woah, at Omotesando station?" Atsushi asked them. 

The others looked at him. 

  "What were you doing there?" Kimizuki asked. 

  "Just to check what is going on there," Atsushi plainly replied. "So, Omotesando station is?" 

  "Yes," Yuichiro responded. 

  "I see. Okay then, I'm ready for anything."
