Biology[]

In his Lightside form, Seiryuu takes on a humanoid appearance, reminiscent of Whyvern King. He has long, dark blue hair, and two cream-colored, short antlers.

His body appears to be clad in a skin-tight black suit, or perhaps countless black scales, over which he wears light blue and green hanfu/kimono-like clothing, as well as a multi-layered dark green belt with gold lining and fluffy fur stitches on the bottom of the belt as well as black sandals. He also wears a golden bracelet.

In his Shadowside form, Seiryuu has the appearance of a dragon, similar to how he appears in the present series. His hair is now a dark blue mane, and his antlers have grown bigger. His scales are light turquoise, and his underside is light blue. He has four limbs, and a crest of the same color as his horns on his chest.

Yo-kai Watch Shadowside: The Return of the Oni King[]

Azure Dragon (Shadowside)

Seiryuu is a supporting Yo-kai in Yo-kai Watch Shadowside: The Return of the Oni King.

Seiryuu is one of the Yo-kai summoned by Summer with the Yo-kai Watch Arcane to aid her in the fight against the Oni King Rasen. He also gives Summer the Keystones for Blizzaria, Rai Oton, and Merameraion. They manage to trap him and then unleash a powerful attack. However, this only reverts him to his De-armoured form, which now possess far higher speed, and they are quickly finished off.

Seiryuu plays a similar role as he does in the anime. Summer recalls being saved from drowning as a child by a mysterious figure when she was younger after she saves a child from drowning while on her way to school.

Later, while Summer, Cole and Bruno are fighting the Onimaro Leader, she shows a key to others that she found on her after being saved when she was younger. Jibanyan crushes the key in his hand, revealing it to be Seiryuu's Keystone. She summons Seiryuu and Bruno is shocked she has the keystone of such a high ranked Yo-kai. Seiryuu fights the Onimaro Leader but holds back when it uses the face of Saki to shock Summer. Seiryuu realises Saki is close to Summer and is taken off guard, being stabbed by the Onimaro Leader. He is later healed by Mitsue and helps weaken the Onimaro Leader before he is felled by Lord Acala.
