A new serialization in the Koha-Ace/GudaGuda-Ace Type Moon Parody series! Koha-Ace is dedicated to reviewing and parodying the recent happenings in the Type-Moon series projects (Fate Series, Tsukihime, etc.), but this time it takes a new twist and gives the scene to showcasing the backstories of its original Servants already known to the readers from Koha-Ace EX: Teito Seihai Kitan, Fate/Grand Order GudaGuda event line-up, and Fate/type Redline. Mysterious Yamatai, bloody Sengoku or the cruel Bakumatsu, their heroes lived lives full of funny antics and difficult dilemmas. _This release also includes special Servant backstory chapters from the previous GudaGuda-Ace 1-3 volumes.
