Ep 4. Yu Kirino

Kunai continues his journey with the adventurer Flan, and they arrive at a port town to find some work. They meet a girl named Yu Kirino who is in dire need of help. Yu's brother is missing and she thinks he's been kidnapped. Kunai decides to help her out and they search the town for clues.

As they investigate, they find out that the local gang is involved in the kidnapping. Kunai and Flan fight the gang members and eventually rescue Yu's brother. However, they soon realize that they have only scratched the surface of the problem. There seems to be a larger conspiracy behind the gang's actions.

Kunai and Flan decide to investigate further and they find out that the gang is working for a higher power. This power is none other than the Church, which seems to be controlling the town's politics and economy. The Church has been using the gang to collect people for their own purposes. They have been taking people with special abilities and either using them for their own gain or killing them off.

Kunai and Flan face off against the Church's elite soldiers, who prove to be formidable opponents. However, Kunai's powers as a demon lord are unmatched and he is able to defeat them. They also manage to save the people who were held captive by the Church.

In the end, Kunai confronts the leader of the Church and accuses him of his crimes. However, the leader is unfazed and tells Kunai that he will never be able to defeat the Church. Kunai, Flan, and Yu Kirino leave the town, but Kunai knows that they will have to return someday to put an end to the Church's tyranny.
