Chariot is a character from Black Rock Shooter’s anime and this model is designed by goncalo-neto.
She is the “other self” of Kagari Izuriha, a childhood friend of Yomi. Kagari can’t walk and bound to her wheelchair all the time although doctor did not find anything wrong with her leg.
Chariot’s weapons of choice are a Sword and Shield making her somewhat look similar to Gundam Talgeese. She also has a spider like tank called Mari.
Chariot’s design look similar to SSN models and personally I like it this way. I think every chibi model should use SSN designs as based.
GoodSmile Company released a nendoroid version of Chariot including Mary back in 3rd April 2013 priced at ¥5,714.
