Micro Magazine Inc. (Chuo-ku, Tokyo) will release 'Swordswoman High School Girl Coliseum' (Novel: Sasadairo Goro, Illustrations: pupps) on September 24, 2026, from GCN Bunko.

A new fantasy novel by Sasadairo Goro, the author of 'I Bought My Childhood Friend Who Was a Slave Because She Was My Sword Training Partner, So I Decided to Protect Her as an S-Rank Adventurer' and 'The 'Human Slayer' Girl Becomes a Bodyguard for a Duchess's Daughter,' will be released by GCN Bunko!

This work is a battle fantasy about a swordswoman, Tenka Renno, who was summoned to another world and participates in the Coliseum to earn her daily bread, fully showcasing her talent.

The Coliseum is a stage for serious battles. Of course, there are elements of sex appeal such as clothes getting disheveled and torn, and the protagonist, who felt 'difficulty in living' in modern Japan, finds her place through battles with rivals... self-discovery and youth elements are also highlights!

Illustrations are handled by pupps, who has worked on many light novels and card games.

Various information will be released in the future, so stay tuned for updates.
