556 was quiet and often teased, but she was loved by everyone. However, her luck was always bad, and she met a tragic end in battle against the black witch.

She was a cutting-edge weapon, unique in the Sisters' Cavalry, which tended to serve as honor guards.

556 was in charge of squad fire support. She shot not to kill, but to protect her allies.



Chiester 556 wears a purple military uniform over a black leotard with white frills. She has short dark purple hair and a pair of bunny ears.


Chiester 556 is very easygoing and has a habit of thanking her comrades for everything they do, even if they insult her.


556 is able to link up with other Chiester Sisters and fire golden arrows.


556 was a new recruit of the Chiester Sisters and got off with a rocky start to 410 and 00, who chastised her for her habit of thanking everybody.

556 was later killed in an unknown battle with an evil witch. From an anti-fantasy perspective, the ceramic bunny belonging to Maria that served as her vessel was destroyed by Rosa.

According to the 07th Expansion All Character Settings Collection, 556 is revived in the Golden Land however she is still afraid to be around Rosa.



Alliance of the Golden Witch

Rosa took one of Maria's bunny figures and smashed it in the weeks before the family meeting. Rosa was in a bad state of mind when she broke it, with Maria speaking of it as the doing of the "black witch." Twilight of the Golden Witch indirectly confirms that the bunny that Rosa smashed was Chiester 556.
