Tomoki Sakura, a tenth‑grade student, is an average orphan, a mediocre academic, and a moderate hentai fan. His motto is "live calmly." He watches over his aimless neighbor and stops the latter"s indecent outbursts with help from childhood friend Sohana Mitzuki. The plot is fairly standard, but since early childhood Tomoki has been having the same dream in which an unknown girl begs for help, saying that she has "been seized by the sky." Reaching a breaking point, the boy turned to Aisiro Sugata – the school"s expert on paranormal phenomena. The senpai clearly explained that Tomoki is linked to the Celestial Realm, which will open tonight. The rest of the answers lie there, so our protagonist settled under an ancient sakura tree for a night shift. When the sky above him opened wide and a beautiful winged woman fell from it, Tomoki realized that his life had not been in vain. Upon waking, the winged wanderer told him she was an angeloid, an entertainment machine named Ikaria, and that from now on Tomoki would be her master, ready to grant any wish she desired. There are no technical limits: if you want, we can make you a millionaire; if you wish, we can destroy the world. But after trying it out, Sakura‑kun quickly understood that every wish will eventually cost something, and Ikaria"s words are not entirely truthful. He would have to deal with those who come after her… And thus Tomoki"s "calm life" began.
