He is surprised to hear her tell him that every Monday the very existence of all her friends disappear from memory. Although he now realises and understands why she is always lonely, he is determined nevertheless to always be her friend, wishing that one day she will finally call him ‘friend.’
In a world like our own, Sensha-do, the art of tank combat or ‘Tankery’ for short, is a traditional Japanese martial art for girls. In every school there is a Tankery Club. Miho Nishizumi, a girl who has a long and proud family history in the art of Tankery, has just transferred into Ōrai Girls’ Academy in Ibaraki Prefecture…to avoid Tankery! The school’s Tankery club is believed to have been non-existent for 20 years! As Miho made new friends and enjoyed the start of her new school life in Ōrai Girls’ Academy, she is suddenly ordered by the student council to revive the school’s dead Tank Club and be their leader. Giving in to the pressure from the student council and her friends, they form the Tankery Club, marking the start of a formidable tank force.
Cromartie High School was a place where population was 100% delinquent, until it suddenly became 1% less. Takashi Kamiyama, is a mild-mannered above-average student, who enrols in the school and regularly writes to his mother about his current student life at school. You’d think that he be bullied non-stop for the rest of his life right? Wrong! As twisted as the logic seems, everyone thinks he is the baddest bad guy in the school, for “only a really tough rabbit would lie down among lions”. As everyone has an average IQ of 50, which is quite low, only hilarious laughs and situations will follow.
