Miss Kobayashi managed to drive Ilulu away, but in return she got a you-know-what attached to her groin with magic. Because of that you-know-what, she starts perceiving behaviors that she would usually think nothing of in a different light and starts getting more and more turned on by Tohru.
I'm betting Ilulu used magic 
to turn me into a guy.
أجزم أنّ إيلولو استخدمت سحراً لتحويلي إلى رجل
Je parie qu’elle m’a lancé un sort
pour me changer en mec.
Suppongo che Ilulu abbia usato
 la magia per rendermi un uomo.
Parece que a Ilulu usou magia
pra me transformar num homem.
И к гадалке не ходи —
 мужиком меня сделала магия Илулу.
