Chachamaru Karakuri.
Personally, she's the bomb digity.
She developed emotions then Negi helped give her a soul.
She is secretly taking Negi away from the rest of the girls while they arn't looking.
and if you question something like "Negi can't be with Chacha because she's a robot and cant have babies." I have this to say,
NEGI GAVE HER A SOUL!
NEGI CAN HAVE CHACHAMARU THROWING BABIES OUT OF HER IF HE WANT!
CAUSE THATS HOW DAMN GOOD NEGI AND CHACHAMARU ARE

Favorite Character?
Mana Tatsumiya!!!!
I love her stoic personality and I have some weird fetish with anime characters with tan skin and black/brown hair
She's the coolest in my book!

honestly....kota-kun's the best.infact his grown up form as kojirou is even better!He is strong,respects women,ANND IZ SO DAMN CUTTTTTE!!!!plus he supported negi alot so GO KOTA KUN!!!!
