Tsuan

Tsuan is a girl who wears her hair in buns and dresses in a blue, Chinese-style outfit known as Spirit Dress: Extreme Death Spirit Dress No. 15. Her looks give off an energetic, martial vibe.

Tsuan has a straightforward and energetic personality.

She is honest, always charging forward without hiding anything.

She enjoys fighting and always seeks stronger opponents.

Instead of tricky plans, Tsuan prefers to face her enemies directly and fairly.

Despite her tough attitude, she shows shy, girlish sides when teased, especially if called something like "gorilla," a comment that makes her mumble that she is not one.

Tsuan travels across different domains looking for strong opponents to battle.

Her skill and battle record have made her famous among many domains.

She used to win just because she was strong, never really facing a close fight—until she joined the battle royale organized by Doll Master of the Tenth Spirit Class.

For the first time, she met someone—Kurumi Tokisaki—who could challenge her head-on, awakening her competitive spirit.

Tsuan's angel is called Heavenly Star Wolf, a weapon combining a massive halberd and a hammer.

If she strikes someone with it, they are destroyed on a molecular level, turning them into dust, just as her nickname "Biscuit Smash" suggests.

She can also throw this weapon with great power.

When using her power, all her senses become sharper, letting her hear the smallest sounds or smell like a dog.

These powers helped her notice secrets others couldn't during the story's final parts.

If her Spirit Dress is broken, the shattered pieces release icy cold energy, freezing everything nearby in an instant.

Tsuan admires and sees Kurumi Tokisaki as her main rival.

Her desire to fight Kurumi grows so intense that it starts to seem a little bit obsessive.

She once became an idol and performed at a concert just to get closer to Kurumi.

Tsuan also has ties with other important characters, like the legendary S-class idol producer Hibiki Higoromo.

She later cooperates with former Domain 9 ruler Kari Rinem in a music unit.

The Legend of the Fighter

Tsuan is known as a mighty semi-spirit who has defeated over 100 opponents.

She travels to many domains searching for stronger enemies and never loses a straightforward fight.

The Battle Royale

Tsuan joins the battle royale arranged by Doll Master, ruler of the Tenth Spirit Class.

During this event, she has her first really tough battle with Kurumi Tokisaki (or someone appearing as her).

This fight is thrilling for Tsuan, as it's her first time meeting a rival who is truly her equal.

Unfortunately, the match ends before a winner is decided, thanks to interference by Doll Master.

They agree to postpone their match, and Tsuan goes back to her original spirit class—though Kurumi has no real plan to keep that promise.

Idol Battle and Unfinished Rivalry

Still obsessed with facing Kurumi again, Tsuan follows her to Domain 9.

There, Domain 9's ruler Mizuho Kizuo gets Tsuan involved in an idol concert that Kurumi and her friends are performing at.

With help from Mizuho, Tsuan makes her debut as a stylish idol and finally "defeats" Kurumi in an unexpected way during the show.

Though her win feels like an ambush rather than a fair fight, which bothers her a lot.

The Idol Unit and New Allies

Recognizing Tsuan's talent, the legendary idol producer Hibiki Higoromo recruits her.

She teams up with Kurumi and Kari Rinem, the former ruler of Domain 9, forming a music unit and successfully putting on a live concert.

More Secrets

In the third volume, it is revealed that Tsuan is also a student of Haraka Kagetsuka, the ruler of Domain 5.

Her growing obsession with Kurumi hints at her changing from a battle maniac to someone a bit yandere.

Tsuan hates being called a "gorilla," though her fighting style is very direct and powerful.

She is called "Biscuit Smash" because of how fast she can crush her enemies to pieces.

She is recognized in every domain because of her travels and battle skills.

"Thank you so much. Because of you, I can become even stronger."

"...Also, I am not a gorilla."
