1.) more amusing
2.) after playing day 8+9 you maybe understand why there is "No" and "Dangerous" but for now let me explain it a little bit.
I am the dev. but i am NOT the person who wrote the ID cards like they are. That was someone in the game. That info + the info that the school is a bit special (beta program, new school system, no real structures and discpliple etc. and). A small amount of employees are the reason why the students from the disciplinary committee created the ID cards.
So... more words need? ^^
When Saki writes satanic signs on the wall, you can be pretty sure bluecat isn't writing satanic signs at wall. It is just Saki.
Every single girl in the game has a own unique personality and maybe the girl(s) who made the id cards thought "oh funny, let's call tomoe's eyes "dangerous" because she is fucking dangerous and scares me!"
and...
"Haha, the blind masae, I wonder what eyecolor she has? Meh, not interested to check out the files. I just write "No" because she probably has no eyes. Dunno. This is so boring. Hope lunchtime comes soon"
