hi, /t/!! i have many theories here for you today, i hope you find them satisfactory.
i think madotsuki has paranoid personality disorder. i have the disorder myself and i always have this feeling people are watching me, which triggered dreams where there are nothing but eyeballs staring at me the entire time.
her not wanting to leave her house could also be proof, as she might be paranoid that someone might want to kill her. (knife effect, toriningen, ect.)
another theory i have is that poniko was a burn victim. her house burned down at night while she was asleep, and the flames were so hot that her face deformed, and dingratiated when the firemen uncovered her body. that is where uboa comes from. madotsuki blamed herself for everything, which is why poniko ignores her. it all happened on a snowy day, which is why her house is in the snow world.
my final theory is about monoko and monoe. they were twins who blacked themselves out from the world, making their own and letting nobody else in. however, madotsuki was determined to be in their world too. monoe was quite sadistic and found it funny when someone lost a limb or was killed. monoko.. she was such a fragile girl. she was too shy to make any friends. on their birthday madotsuki decided to pay them a visit to show them they weren't alone in the world, however she saw monoe exit their apartment with monoko and decided to investigate. monoe led monoko to the rooftop for a "special git" it sounded like. however, her gift was her demise. monoe pushed monoko off the building, and because it was so high, blood and bones were visibly out of her body when she crashed, killing her instantly, leaving a smirk on monoe's face.
what do you think, /t/?
Wow! These are really great!
I have signs of paranoia and I get nasty panic attacks when I go outside (I also have some form of personality disorder that I really don't understand).
The idea that Momoe killed Monoko is really creepy and kinda sick, but then again, it's better than yet another rape theory.
