Chen Yakumo

Chen Yakumo (八雲 橙) is initially introduced as a minor ally who joins the group when she stows away on their boat in Hong Kong, she becomes a core ally in the second half of the story, gaining a Standmaku called Survivor.

Appearance
Chen is an approximately 10 years old, of average height and thin to medium build.

She has short, brown hair; a small, slightly upturned nose, and red eyes. She commonly wears a red dress and a white long sleeved shirt and a green mob cap, later becoming a shorter sleeved shirt when she rejoins the group in Egypt.

Personality
Chen presents herself as a temperamental and irreverent brat, becoming annoyed when Kaguya questioned her about being a youkai. On one occasion, she challenged all five of the members of the group with only a small knife when they were considering what to do with her, pretending to be cold-blooded killer.

Brave but reckless, she gathered the courage to flee from home and travel the world. Her bravado doesn't prepare her for the Standmaku she meets. As foretold by Kaguya, Chen still only drags the group down to the point of risking their own lives, especially in the battle against Speed King, where she screams for help instead of using the time she had to run. Eirin eventually tells Chen that she is going to give her money, plane tickets and send her back to Gensokyo as soon as possible. Despite her protests, she is left with no other choice and finally returns home, or so they think.

Chen later returns to the scene aboard a Yagokoro-sponsored helicopter in the middle of the desert, brought by the Yagokoro Foundation to help in the battle against PADIO. There, she reveal her newly acquired Standmaku, Survivor.

Chen values her independence, and she has a high opinion of herself, especially after gaining Survivor, thinking herself and hier Standmaku to be stronger than Kaguya and Star Sapphire.

Chen nonetheless has some standards, notably being willing to fight with Cirno to save a cat-lover child. She also selflessly sacrifies herself against Flandre Scarlet to save Youmu.
