Turns out the one spreading the rumors was Hashimoto, who did so at the behest of Sakayanagi. Shortly thereafter, Sakayanagi appears before Class C and she informs them she has evidence regarding the rumors about Ichinose.
It seems my school life is 
finally about to get exciting.
يبدو أنّ حياتي المدرسيّة
ستصبح حماسيّة أخيراً
Endlich hat dieses triste
Schulleben ein Ende.
Por fin le pondré fin
a mi aburrida vida escolar.
Por fin le pondré fin
a mi aburrida vida escolar.
Grâce à cela,
Così, finalmente...
Parece que minha vida escolar finalmente
está prestes a ficar empolgante.
Наконец-то в школе…
станет интересно!
