King from Now On!

When ordinary high school student Yuri Shibuya defends a classmate from some bullies, he winds up dunked in a toilet that somehow transports him to a strange land, where he is told that he's the new Demon King!

After a heated exchange over an insult to his mother, Yuri discovers he's mistakenly proposed marriage... to Lord Wolfram!

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...

Arriving on Van Da Via Island, Yuri, and the others hear of a tale of a cursed hot spring and believe it could be where they'll find Morgif, the Demon Sword.

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.

As the morning comes, everything appears quiet despite the commotion the night before, but it is soon discovered that the gem of the Dragon King was stolen from the crown in the treasure room!

Stoffel and Raven begin the next phase of their plan when Yuri investigates the theft of the gem, forcing Conrad and Wolfram to come to his rescue!

Having captured Yuri, Stoffel tries to convince him to join his side, but Josak sneaks him out as the two armies prepare for battle...

While on a trip to find an imposter Demon King, Yuri, Conrad, and Wolfram come across Gwendal, and an encounter with a Sand Bear separates the group into two pairs.

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.

With Norika reuniting with her son, Yuri discovered the other piece of the Demon Flute and decides to see what it can do.

Yuri heads into a city after hearing of a stolen demon stone, finding it in the hands of a poor family that has been using it to earn money for food, leading Yuri to decide to help them out.

After announcing her intention to marry Raven, Celi's past and her connection to Raven and Stoffel are revealed, while Yuri and the others are invited to a celebration.

The castle's guest house has been taken over by monsters, so Yuri, who wants to get a night of peace away from Wolfram, resolves to clear it of the unwanted guests.

Deciding he wants to see a dragon, Yuri sets out with Wolfram, Conrad, and Gunter travel to a preserve where they discover dragon poachers, and one of them challenges Yuri to a fight!

After his defeat in battle, the poacher reveals his name to be Alford, who explains his motivation to fight Yuri while the group makes plans to protect the dragons.

During a visit from Nicola, someone arrives at the castle claiming to be Yuri's illegitimate child!

Despite his twisted ankle, Yuri takes Greta into town and gets captured by some thugs, but after being saved by Wolfram and Conrad, they are attacked by a masked man!
