Gakkatsu!

(Esta sinopse está em inglês. Ajude a comunidade traduzindo!)

---

In a fictional school, "Tender Tank" Rareko is constantly opening absurd yet strangely enthusiastic debates, this way creating a lively classroom life. Bringing up tremendous themes, she and her classmates exchange words like sword-strokes, and here and there even a profound remark is slipped in.

A fun and informative debate comedy, packed into only five minutes each time.
