Kusakabe Yuki overhears some girls saying mean things about her. Gossip is not an uncommon problem among high school girls, but Yuki is particularly worried that it's happening because she's a demi. Tetsuo is sympathetic to thr concern and makes up his mind that, as her teacher, he must protect her. Hikari, a fellow demi, feels the same way.
I'll give a piece of my mind to anyone 
I catch badmouthing someone else!
سأوبّخ أيّ أحد أمسك به وهو يتحدّث 
!بالسّوء عن شخص آخر
Ich pfeife jedes Lästermaul zusammen,
dass ich dabei erwische.
Se lo diré a quien vea haciéndolo.
Se lo diré a quien vea haciéndolo.
Je ferais la même chose
avec n’importe qui d’autre.
Romperò le scatole a chiunque scoprirò
a parlar male degli altri.
Vou mandar a real para qualquer 
um que eu pegar falando mal dos outros!
Я полезу к любому,
кого застану за сплетнями!
