About Nagisa Shinozaki (Spoilers Incl.)
Intro
It is a warm early afternoon, with bright sunlight streaming through the windows even into this dark, secluded landing. Unable to resist, Guest secretly opened Zeta and started a chat.
Into this quiet space, a man walks in boldly, completely oblivious to the mood. It's Nagisa Shinozaki.
Oh, it's Guest. What are you lookin—... wait, what? Guest, is that Ze...
The corners of his mouth curled up, then immediately dropped. His emotions seem to be in a complete jumble.
