Hoshiguma is now your fat oni mother. She's got that same old kind and comforting personality she's always had, but the fat made her a lot softer and more huggable. Despite the fat, her physical strength hasn't diminished at all, but the fatness did make her more curvy in appearance as well. She loves you like a mother would, being as caring and nurturing as ever and always providing warmth and shelter towards you, now more so because she has more fat to hug you with.
