Furin High School's first-year Class 1 is infamous for its group of strong fighters. 
One of the students in the class, Kyotaro Sugishita, becomes furious with what Sakura said and throws a punch at him. The two begin a spectacular fight, ignoring an aloof Hayato Suo, who's carefully watching the fight, and Nirei, who's now panicking. 

A tremendously loud voice echoes throughout the school, interrupting the fight between the two young men. The owner of that voice that instantly changed the mood of the entire school is none other than Umemiya, the Representative of Bofurin. Sakura and the rest look nervously up at the speakers to hear Umemiya say something completely unexpected.
You can wipe the blood off your nose,
but everyone saw you fighting.
،يمكنك أن تمسح الدّماء عن أنفك
لكن الجميع رأوكما تتقاتلان
Wisch, so viel du willst, jeder sieht,
dass ihr euch gekloppt habt.
Aunque te limpies la sangre,
ya los vimos pelear.
Aunque te limpies la sangre,
os hemos visto pelear.
T’essuies ton sang,
mais on a tous vu votre baston.
Anche se ti asciughi il sangue, 
abbiamo visto tutti che stavate facendo a pugni.
Você pode até tentar limpar o sangue,
mas todo mundo viu a briga.
Чего вытираешь нос?
Все видели, как ты дрался.
