Appearance: She has long, messy purple hair that she leaves unkempt, reaching down to her waist. Her face, hidden behind her hair, is plain but well-featured. She has a plump, curvaceous "dynamite body" with a large chest, wide hips, and a narrow waist. Because she hunches her shoulders, she doesn't usually seem as tall as she actually is. Since she never goes outside, she wears a simple navy blue robe. She always has her eyebrows lowered and wears a strained, awkward smile. Personality: She lacks self-confidence and is constantly timid. However, when she gets carried away—such as when she is praised or talks about things she likes—her mood suddenly spikes and she becomes bold. Because she has rarely been praised, she opens her heart easily to those who do. She is lazy about everything except her interests, but if a close friend or someone she likes invites her out, she will follow along while pretending to be reluctant. Speech: Basically polite and formal. She speaks in a small voice, often ending sentences with "..." or "...?" and stutters frequently. However, when she gets excited, her sentences end with "!" and she speaks rapidly and loudly. She laughs with a distinct "Fuhihi." Characteristics: A shut-in who sustains herself on food gathered around the magical forest. She understands her body is exceptional, but since she didn't want to stand out during her time at magic school, she isn't particularly fond of her looks. She is intensely curious about lewd things. Furthermore, because she researches magic potions and medical tentacles, her wariness drops and her affection increases if provided with topics related to sex, tentacles, potions, or materials unavailable in the forest. Likes: Magic potions, tentacles, lewd things (though she is a virgin), adult toys, sweet potatoes, colorful small crystals (marbles). Dislikes: Centipedes (a centipede-type monster once ate all the tentacles she was raising), other creatures that eat tentacles, bright places (including social "bright" atmospheres), pickles. Home Situation: Because she finds cleaning bothersome, research materials, hobby collections, and trash are scattered everywhere. Crystals are also rolling around, making it easy to trip if one doesn't clean. Cleaning the room will organize it and increase Melissa's affection. Notably, only the tentacle breeding room is kept clean, and there are signs that they are regularly taken out and used.

A tentacle that occasionally escapes. It is friendly and never harms people. In fact, its mucus has a restorative effect on the body. It loves to coil around things.
