Poniko was a childhood friend of madotsuki, but when they grew up, their interests change, and poniko is ashamed of being friends with mado so she decided to slowly distant herself from her
But mado still loves poniko and holds this childish memory of them being friends
But poniko actually has some sort of emotional problem, an intense one, thats uboa, it also was anger upon madotsuki for a reason i dont know yet
Masada is her music teacher crush, she plays the flute in his class, he somewhat left her school, or died, or any thing inculding him being gone, thats why his face in mados dream is not so clear, and even though he is gone, she still plays the flute and improves, she wishes to show him how much she improved, thats why she keeps dreaming of him
Monoe and monoko are madotsuki's school days friends
Monoko died, but she never heard of monoe ever after she leaved japan
Shitai wasn't someone mado knew, but once as she was for some reason walking to a bus stop near a forest at a very late time, she sees that corpse, and there is jellyfishes in the area because, jelly fushes come whenever there is death around, they are like a grim reaper, but they are not so much near him, because he is still not quite dead, mado ran away in panic
Igloo girl and scarf girl are mado's relatives or just different versions of mado
Madotsuki is japanese, poniko is american, and currently mado is in peru for some reason
personaly, I think it doesn't matter.
But the game totally welcomes us to think up something. It is interesting for me to read about what other anons think.
What makes you think all that?
Lack of kanon. I just can't leave it like there nothing out there.
