Description
Erio Touwa is the daughter of Meme Touwa and cousin to Makoto Niwa. After vanishing inexplicably for six months, she was discovered floating in the sea with no memory of her absence. This event sparked an intense preoccupation with extraterrestrial phenomena, leading her to identify as an alien researcher observing humanity. An incident where she fractured her leg attempting to levitate on her bicycle prompted her to begin enveloping herself in a futon as emotional insulation. Her mother, Meme, initially responded by largely ignoring her presence.

Erio possesses light blue hair reaching her ankles, often slightly disheveled with distinctive hair antennae, and deep blue eyes. She frequently appears barefoot, even outdoors. When first encountered, she is almost entirely concealed within a pink futon adorned with purple floral patterns, revealing only her legs or hair tips. Later, she emerges wearing an unkempt school uniform: a partially buttoned shirt, loose bow tie, and skirt.

Initially withdrawn and emotionally detached, Erio communicates primarily in monotone scientific jargon while maintaining her belief in extraterrestrial origins. She exhibits minimal social skills and avoids interaction. A pivotal shift occurs when Makoto challenges her alien identity by deliberately crashing a bicycle to demonstrate her inability to fly. This confrontation forces her to acknowledge her humanity, causing initial distress. Subsequently, she gradually reduces her reliance on the futon, using it only during discomfort or anxiety, and begins engaging in conventional activities. She secures employment at her great-grandmother Tamura's sweets shop, where her interest in aliens is understood, and joins a community baseball team to spend time with Makoto. She also develops a fondness for stargazing, documenting celestial observations in a notebook during nighttime outings with Makoto.

Erio's relationship with her mother evolves from mutual avoidance. Meme, who initially advised Makoto to pretend Erio didn't exist, later supports her reintegration by arranging her job and participating in family activities. Her background includes a father named Elliot, referenced briefly concerning Meme's past, and great-grandmother Tamura, who shares Erio's alien fascination. The mystery of her six-month disappearance remains unresolved.

Her development culminates in a gradual embrace of ordinary life while retaining traces of her unique perspective. She forms a close bond with Makoto, whose engagement helps her navigate social challenges. Though she ceases to identify as an alien, her curiosity about the cosmos endures, reflecting a bridge between her past beliefs and evolving human connections.
