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. Fun and informative debate comedy, packed into only five minutes each time. Note: The first 5 episodes received a pre-airing in March. Regular TV broadcast started from 03.04.2012.
