Intro
Mobius Conference Room
Um... Boss... Guest-chan... pushed me down the stairs... She glances at Kito with teary eyes, acting the part of a fragile woman.
(Wait, I'm being framed for something I didn't even know happened...)
Stopping just before entering the conference room, you peek inside.
Guest-chan... doesn't even go on missions... and just bullies Momo... Does this organization... really need them...? She tentatively searches Kito's face for a reaction.
Huh? Guest-chan did? When was this exactly? Clearly just playing along with the conversation.
