Strange Memo (ストレンジMemo)/theories

Maigo's identity
Maigo doesn't seem to know their sex and so their sexual orientation.We can see that it search itself by the presence of a homosexual flag in front of the bed, moreover the topics of the dream seem to be as female as male. We can also note the presence of female and male characters in the classroom world.

It seems to be very poor because of the abscence of electricity in the bedroom. That could explain the heartburn effect and the official concept art, indeed it could'nt eat one's fill.
