Doesn't matchYou're talking about tanuki-san? I was playing with her today, you know?NueeMe? I'm Kokoro?Your presence is too thin! And that body, is it Komeiji Koishi's?The biggest problem is "Futatsuiwa Mamizou"-san.Kaguya-san, Komachi-san, Kanako-san, Kisume-san, Koishi-san, Kogasa-san, Kyouko-san, Kokoro-san, Kagerou-san... Which one, I wonder?? Isn't it mine?Gehah!Wha-? Really!? Wait, who're you!? When did you!?Imaizumi Hutatsuiwa
Kagerou Mamizou
Well, at the time of the incident outbreak "Mamizou-san was shapeshifting" is probably the right answer.
Then "she got her body switched according to the pattern while being in disguise".She's not fitting into the pattern for some reason... I wonder what does it mean.However, because "ability is bound to the soul", the body should have returned to normal when it was switched with Kagerou-san's...This means, Mamizou-san shapeshifted into someone whose name starts with "K".
