PERSONALITY NOTES

Usually she's unexpressive and quiet. She hates when people talk about their dreams because she considers them weak.

Marion The Puppet Master, fights manipulating a puppet named Chuck, the channel of her OverSoul, that she uses instead of the Oracle Bell.
She's a bit egoist and outlandish. At the first sight, she seems to have a quiet personality, but her expression could change suddenly, showing all the hate that she hides in herself.
Her coldness is the sign of the sad past that all the Hanagumi's members have in common.
She laughs covering her face with the hands and her personality is in clear contrast with the one of Matilda.
