Kunihiko is an adventurer and Asaka's childhood friend, both before and after reincarnating.

Personality
Kunihiko is rash and some time has a tendency to act without thinking too much. Due to living as an adventurer he also has a very mature point of view.

Synopsis
In his past life, apart from maintaining his delicate but inseparable relationship with his childhood friend, he was a completely normal high school boy.

Born along Asaka in a village on the border between the humans and demons. They took bandit-like actions against the Demon. Being stuck with that inseparable relationship with his childhood friend after reincarnating is some kind of fate. In order to defeat Merazophis, the leader of the Demon that destroyed that village, he became an adventurer and gained fame. While he accomplished his heart’s desire of fighting against Merazophis in the Human-Demon Great War, he was unable to overturn the overwhelming difference in strength, and withdrew. He keenly felt his own lack of ability. Afterwards he went to the Elf Village, and got dragged into the war between the elves and the Demon Lord Army.
