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.
Even if you've forgotten
Whose words they are
Auch wenn du schon vergessen hast,
wie du das in Worte fassen sollst.
Quand bien même tu ne te souviens pas
de qui tu tiens ces mots.
Mesmo que você tenha se
esquecido das palavras de alguém
Не страшно, если ты забудешь,
кто это сказал.
