Marshmallow-Sweet “Dreamer Girl” Kamiogi Academy second-year and the proud new owner of Marshmallow Tree.

A perky idealist, her relentless positivity can also read as plain airheaded at times. While not the most naturally gifted at running a business, her smile and straightforward way of warming up to others never fail to win her new fans.

Ever ready to lend a helping hand, lost cats and dogs are such a soft spot for her that she has a habit of bringing strays into the shop. In fact, she even “adopts” the protagonist after finding him collapsed and homeless in a nearby park...

Dependable, Vertically Challenged “Big Sister” Kamioga Academy third-year and Marshmallow Tree’s manager-cum-pastry chef.

Easily underestimated because of her small stature, she’s actually a sensible “big sister” type, at times even bordering on maternalistic.

While her talents as an artist have made her a household name practically overnight, the pressure she feels to complete her next big book has sunk her into a major creative slump. She’s also a huge fan of cakes and tea, and as such, is a frequent customer at Marshmallow Tree.

Her public persona is that of a mysterious, unapproachable “ice queen”; in reality, she talks like a tired office worker with a bewilderingly hit-or-miss sense of humor.

Half-Finnish and half-Japanese, she relocated to Japan only a few years ago, but seems to have already lost her passion for baking cakes...
