DearS

Crossing over a bridge, an unidentified box truck overturns at the sight of a stray cat in the road, spilling a human capsule from its cargo (which shows Exposition). On his way back from school, Takeya encounters and rescues a mysterious Dears from being run over by a delivery truck. After proclaiming servility to him, and then shortly fainting, he takes her to his apartment where she is washed, clothed, fed melonpan and given the name Ren. Meanwhile back at the bridge, Rubi and Khi discover the lost capsule.

After a nightmarish and erratic morning, Neneko mistakenly discovers Ren during an unexpected visit, and examining the situation, assigns Takeya the job of teaching her Japanese. He indifferently teaches her nothing and eventually falls asleep, during which time Ren telepathically learns all the material and gains the ability to speak the language, though in a slightly broken manner. In this more fluent condition, Neneko and Takeya bring Ren to a mall to shop for new clothes. Elsewhere, Miu finishes up her admission to Koharu High with Khi.

Miu acquaints with her assigned homestay, an elderly couple she warmheartedly calls her grandparents. Meanwhile, after being scolded by Takeya for her nakedness, Ren decides to clean the apartment by defenestrating his furniture and trash; Neneko empathetically awarding her yesterdays shopping change in return. Xaki instructs Nia to apprehend Ren. The following morning Ren visits the market, and drawn by the scent of melonpan, buys a bag of it; Nia botching her capture and leaving absentmindedly. Ren affectionately visits Takeya at school, causing an uproar that settles when she is believed to be a substitute for Miu. Tired and confused, Takeya and Ren retreat home.

Ren begins her first day of school and assimilates quite nicely; she is well respected and admired by everyone. When Miu arrives, only to learn of her replacement, she charges Ren; refusing to coincide with her as the student diplomat. In response, the school holds three duels: a 100 yard dash, a liberal arts test and a cookoff. While Miu effectively wins 3-1, she mournfully forfeits the last challenge. Nevertheless, the principle asks both girls to stay; Miu vowing to watch Ren attentively.

Detached and confused about Ren, Takeya grows increasingly rash towards her. Miu helps to explain the situation and supervises her after class. That night, Khi visits Miu to collect information on Ren while, back at the apartment, uncontrollably aroused by her body, and sensing this, Ren straddles a distraught Takeya.

Takeya stops Ren from sexually advancing, calling it too soon. Slightly awkward from this, he distances himself from her for most of the day. Miu invites herself to reform Ren by showing her to cook and gaily decorating the apartment. As Takeya throws out the flashy new room additions, he is hastily tackled by his stepsister, Natsuki Ikuhara.
