Keikenchi

GUDAGUDA Taikou Legend ZIPANG (ぐだぐだ太閤伝ZIPANG) is a manga written and illustrated by Keikenchi, serialized on the magazine Comptiq and the web magazine TYPE-MOON Comic Ace. It is a side story of Koha-Ace serialized in 2022 featuring a Holy Grail War set during the Sengoku period.

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.
