Seishuu Ri

Seishuu Ri (李青秀, Ri Seishū) is a Dungeon Monster and part of Kouen Ren's Household Members.

Appearance
Seishuu's main feature is his hair, which is made of snakes. He's taller than an ordinary person, has pointed ears, wears Kou's traditional clothing and has a shoulder protector on his right shoulder.

History
He once was in a Dungeon, but Kouen Ren conquered it and for some reason he decided to serve him as his Household Member.

Second Sindria Arc
Seishuu Ri is shown for first time in the army's base in Balbadd, behind Kouen, along with other members of Kou's army.

World Exploration Arc
Seishuu attends at the Emperor's funeral and is located with the rest of the court, with the traditional mourning attire.

When a priest reads the testament and Gyokuen Ren is appointed the next Emperor, he, Shou En, Kin Gaku and Kokuton Shuu rise up, enraged, because Kouen was supposed to be the next Emperor. Seishuu and the others listen at Gyokuen's explanation of her being the next Emperor instead of Kouen, but they know they have been fooled. Immediately after that, the court splits in two, with Gyokuen and the Imperial Priests in a side, and the army and the Imperial Family in the other.

Magnostadt Arc
Alibaba Saluja is fighting against the Black Djinn, and is about to use his Extreme Magic to eliminate them when Shou En advances to his move and destroys them with a breath of fire. After that, Kouen and the other monsters make their appearance riding carpets. Kouen analyzes the situation and, when he sees Kouha Ren's state, says to his Household that if the the enemies are too much for the others, they will deal with them with their strength. The four monsters roar in approval.

Seishuu, Kin Gaku and Kokuton Shuu head towards the Black Djinn. Seishuu says to Kokuton and Kin that they have to take the Black Djinn down on their own for not to make Kouen's hands get dirty with their filthy blood. Kin hits him on the head, and asks why is Seishuu giving orders, calling him fucking snake brat. Seishuu complains, saying that this hurts. Then, they activate their Household and become huge monsters. With the snakes of his hair he catches and shatters the Black Djinn.

Abilities

Djinn

 * Seishuu uses the powers of one of Kouen Ren's Djinn, Astaroth, but is still unknown which effects has.

Household Vessel
By saying this phrase, Seishuu takes on an even more monstrous appearance. He becomes larger, and so does the snakes he has for hair. The snakes are now able to wrap around and bite/eat things as large as a Black Djinn.
 * Seishuu has a Household Vessel from one of Kouen's Djinn. It is in the form of a bracelet. "Come, Household Born From Astaroth, I Consecrate My Body To You, Become One With Me!!"

Trivia

 * His name means Beautiful Blue in Japanese. His last name means Plum.
 * The design of his hair may be inspired by Medusa of Greek mythology.
 * He shares the same family name of Seisyun Ri and Seiryuu Ri, which could mean that he was adopted into the Ri family.
