Yarinaoshi Crank-In

Nekoyashiki Tora is a genius author who can write an entire novel in seven days and is known as "The God Who Creates Worlds." But his true identity? A complete hikikomori in his thirties. One day, when he collapses from overwork, his sister, Neko - a pharmaceutical researcher - administers an experimental immortality drug that she has been developing, making Tora young again! Forced by his sister's arrangements, Tora ends up attending school. While living out the youth that he could only fantasize about when he was a hikikomori, he has a fateful encounter. "If you live even though you want to die, then fire up and burn your life! Leave proof of your existence in this world, and impress me to death!" A provocative speech held at the school club promotion event. Words with strong conviction, spoken by the refined and beautiful Kandori Ruka, president of the school's Film Club. Captivated by her overwhelming charm, Tora pulls an all-nighter to write a screenplay. Rather than creating an entire world in seven days, this time he wants to create a single cute heroine. Tora, who had always created works only for himself, now creates for someone else for the first time. With his youth restored, Tora is plunged into new dreams and challenges...
