page 15 : michiru is wearing the black gloves .
page 17 : michiru is not wearing the black gloves .
maybe this is a goof . or michiru just takes off her gloves to hold pii-chan .
i think michiru is silly because she loves a caterpillar too much .
a caterpillar 's life-span is very short , it can only live for a few days , a few weeks , or a few months .
page 21 :
- hana : i wonder what pan/breads they have today .
page 23 :
michiru is the only girl who doesnt eat anything because she doesnt want to gain more weight .
last pages :
michiru is holding a pencil , i guess this is the pencil that miko used during the drawing class .
maybe michiru actually has no evil intent , she just wants to draw hana with this pencil , lol .
yoh is the sister of michiru . i guess yoh comes to the school because :
a / she wants to kill miko , ASAP , lol .
b / or she wants to protect hana from michiru , actually .
my theory :
plot twist : yoh is actually a good girl . maybe she knows about the octopus ghost , or maybe she knows that michiru is a dangerous , unstable yandere , so she wants to protect other peoples from michiru .
yoh keeps the dangerous michiru on a short leash to control her , and yoh doesnt want michiru to spend too much time with other peoples .
i guess in michiru 's previous school , she also loved someone , then she became mad and stabbed someone with a metal pen , so then she had to change school .
yoh finds the stabbed photo of hana , so yoh knows that michiru wants to stab hana , so yoh comes to the school to prevent that .
