Those who the Tamakoma Branch members happened to meet at a barbecue restaurant are Ninomiya Squad agents, their opponents in B-Rank Wars Round 8.
After getting back to the branch office, Osamu and the other members start developing plans for their final match.  However, a question posed by Hyuse to Chika creates a ripple.
and my classmates,
none of them believed me.
وزملائي في الصفّ، لم يصدّقني أحد منهم
noch meine Klassenkameraden
wollten mir glauben.
mis compañeros… nadie me creyó.
mis compañeros… nadie me creyó.
Ni personne de ma classe…
Personne ne m’a crue.
e anche ai miei compagni di classe, 
ma nessuno mi credette.
e meus colegas de classe,
nenhum deles acreditou em mim.
ни одноклассники мне не поверили.
