Written by: 麒麟堂 あみだ
Synopsis:
Summoned to another world, there’s me, Yamada Ichiro, and the scheming pretty boy, Ryuguin.
The appraisal results reveal that Ryuguin is the Hero, and I’m the Holy Knight.
While Hero Ryuguin lazes about without putting in any effort, I repeatedly venture into dungeons to save the world, always ending up battered and covered in wounds.
Even though I help the heroines grow and forge bonds with them as we survive near-death experiences together, for some reason they all fall head over heels for Ryuguin. Right in front of my eyes, they confess to him and leap into his embrace.
Ryuguin’s harem just keeps growing.
This is the story of how I escape from Ryuguin’s harem party and start doing things my own way.
