When Gwendal and Conrad go off to protect a village under attack, Yuri learns the truth of the battle and resolves to become the Demon King to put an end to the fighting.

Having returned to Earth, Yuri resumes his normal life and returns to baseball practice, while his mother reminisces about the past.

While enjoying a party at sea during a trip to Van Da Via Island, the ship is attacked by pirates, forcing Yuri to unleash his magic once again...

Josak fools Yuri into a fight to the death to power up Morgif by absorbing souls, but his opponent is Rick, the young apprentice from the ship!

With Yuri back on Earth once more, Stoffel, former regent to the previous Demon Queen, begins to hatch a plan to demonstrate how much Yuri will need him.

Arriving in Svelera, Yuri and Gwendal meet a runaway bride who reveals she has the Demon Flute, but when Yuri tries to use it, it doesn't work!

Gwendal and Yuri are put on trial over their "relationship" and when Yuri is unable to harm Gwendal to save himself, he is sentenced to hard labor in a mine filled with esoteric stones that suppress demon magic.
