Sin Dragoon Coronation

"The bonds you have with those you care about. That's your treasure, and now your strength!"

- Ophelia to Ichijou Tsukino Sin Dragon Coronation, also known as Red Dragon Emperor's Seven-Star Arsenal, is a specialized technique used by Ichijou Tsukino from the Highschool DxD: Яe-birth continuity. By "channeling" and "linking" the Evil Pieces from his fellow peerage members, Ichijou can change his Scale Mail armor into seven different forms based on the individual abilities of his comrades.

Summary
During the initial events of Volume 8 of the fanfiction, the demon Lord Mary Beelzebub noted that, even as a Mutation Piece, Ichijou's Queen Evil piece was being rewritten and overwritten by a different code, speculating to be the abnormal growth of Ichijou and the several moments which he almost triggered Juggernaut Drive, in reality being the fusion between his power, Yagura's, Ddraig's and Ophelia's, which she remodelled herself in order to both better adapt to the power of the red dragon emperor and test a prototype improvement over the tradicional system.

During the events of the Vampire-Devil Meeting arc, using the link he has as a Queen, Ichijou awakened a new technique by using Ophelia's link technique on his fellow peerage members and himself that allows him to transform his Scale Mail armor into seven different forms based on his allies, basing it on Issei's own Illegal Move Triaina.

Abilities
Sin Dragon Coronation has the ability to change Ichijou's Scale Mail armor into seven different forms based on the Evil Pìeces of Berolina's Peerage. Much more like Crimson Queen Gear Drive, ichijou can use the Strength of his own Queen Piece to morph it into different pieces and, using Ophelia's linking ability, "borrow" some abilities and attributes from his fellow peerage members.
