Description
Makoto Niwa, a 16-year-old high school student, relocates to a new city to reside with his aunt, Meme Tōwa, after his parents depart overseas. Anticipating routine teenage life, he instead discovers his cousin Erio—a self-proclaimed alien who isolates herself beneath a futon—prompting him to pivot from ordinary concerns to aiding her fragile reintegration into society. Amid this mission, he navigates eccentric family dynamics and classmates who disrupt his equilibrium.

Renowned for dry wit and meta-aware observations, Makoto dissects his experiences through introspective monologues. He meticulously tracks "adolescence points," a self-invented metric gauging social exchanges with female peers, though mounting doubts about its relevance shadow his maturation. While positioning himself as the grounded foil to Meme’s whimsy and Erio’s delusions, fleeting cracks in his stoicism surface—awkward blushes at Meme’s teasing or quiet fascination with life’s oddities.

His bond with Erio transforms from bafflement to determined advocacy. He methodically dismantles her alien narrative, intercepting ill-fated attempts to "fly" from bicycles, yet wrestles with guilt over eroding her emotional shields. Similar tensions arise in interactions with classmates Ryūko Mifune and Maekawa, whose romantic overtures weave subtle harem undertones into his life, met with sporadic obliviousness.

Joining a community baseball team with Erio and Meme sparks broader social ties, climaxing in a high-stakes game interwoven with town festivities. As Makoto evolves, his fixation on point-scoring crumbles, replaced by valuing authentic bonds. Lingering mysteries—like Yashiro Hoshimiya’s extraterrestrial assertions and a prophetic meteor strike—chip at his skepticism, forcing him to confront rigid pragmatism.

Progressing from aloof commentator to engaged catalyst, Makoto mediates between logic and eccentricity, aiding Erio’s tentative steps toward employment and school despite her notoriety. His dynamic with Meme oscillates between exasperation at her antics and grudging acknowledgment of her latent insight, mirroring his nuanced navigation of kinship and self-discovery.
