>Atri attacked a student in a school 31 years ago
Didn't expect that... but you know what? am sure it's the student's fault @_@ why would she go to a school and attack only 1 of them? he gotta have done something... but does that mean her old master was someone in school 31 years ago?... i think it can still be one of Natsuki's parents... maybe they were studying there and one of the students hurt them, so Atri went there to help them? i can see this happening @_@ this gotta be why her master helped her and maybe then entrusted her to the grandma living in this place far away from prying eyes... Atri-chan did nothing wrong!!!
