The Adventure of Hero Kairu (勇者カイルの冒険)

Villager Kairu had 2 dreams.
To become a knight and protect the kingdom from monsters…and to have sex with all the cute girls around.
After arduous training at the knight academy, he is able to fulfill his first dream.
And soon, an arduous twist of fate will find him acquiring the title of \”hero\”
which will allow him to fulfill his second one.
For the \”hero\” possesses the authority to force any lady in the land to have sex with him.
Let’s hope knight Kairu remembers to protect the kingdom in between all his ejaculating…
