Gorou, a first-year high school student at a private high school in Tokyo, has no "hopes," no "dreams," and no "ambitions." The world is "indifferent" to him, and he spends his boring, unchanging days with his best friend Akitsu while having a faint longing for Honoka, a classmate at the same school. One day, Gorou receives a strange notification on his smartphone. "You have been chosen. Please make a wish." Gorou thought it was malicious spam, so he tweeted, "I want to do something naughty with my idol Honoka." The next day, he is invited by Honoka to pull down his pants in a deserted arcade... "Congratulations on the fulfillment of your great desire!" Then, a mysterious girl, Lall, suddenly appears. Confused by the series of events, Gorou is told of a cruel fate. Gorou was chosen by the "Great Will" to fulfill his wish, and in order to do so, he and the other Kamisama (God) candidates would kill each other for the title of "God" until there was only one left. The first candidate to appear as a potential Kamisama was, of course, Honoka, whom Gorou had longed for. What choice did Gorou make against Honoka, who attacked him mercilessly?

Years ago, astronaut Byakuya left behind precious materials in the belief that his son, the scientifically-gifted Senkuu, would one day find them. In the present, the Kingdom of Science's Kohaku and Ginrou have infiltrated the harem of the Petrification Kingdom’s leader with the help of Amaryllis, a local girl. At first, their mission progresses without a hitch. Unfortunately, an error enacted by Kohaku and Ginrou leads Minister Ibara and the Island’s strongest warrior, Moz, to identify the intruding duo as enemies. Even worse, Moz tails Amaryllis when she returns to inform Senkuu of the news, discovering the scientist's secret hideout. However, Moz's agenda does not align with Ibara's—he wants to dethrone the minister and keep the petrification device for himself. If Senkuu plays his cards right, he could gain a powerful ally and win the war once and for all.

A high school loner is given the part-time job of a lifetime as a modern day ninja tasked to perform international assassinations. After World War II, Allied Command in Japan developed a new agency to help manage terrorism and violence within the Pacific region. The agency was staffed with ninja and they were initially tasked to handle domestic affairs. Eventually that program grew to its current form, managing 20,000 ninja across a range of domestic and international affairs. One of those ninjas happens to be Kudo. The seventeen-year-old high school loser is now poised to be the next line of defense against a potential surge in foreign assassins invading Tokyo.

After losing his leg as a newbie adventurer, he retired and returned to his hometown in the countryside. Doing things such as collecting medicinal herbs, exterminating magic beasts and wild beasts, and helping with the villagers' farm work, it's hard to decide whether to call our protagonist an adventurer or a handyman. And while doing these things his age quickly approached thirty. One day while searching the mountains for herbs, he discovered an abandoned child. Thinking that he couldn't just leave it, he took it home and raised it until his age approached forty. His now grown-up daughter had also wanted to become an adventurer, likely from growing up watching her father. Although her father had taught her the sword since she was young for self-defense, her talent at it was quite impressive. Thinking that it would be better for her not to be stuck out in the country for the rest of her life, our protagonist sent her to the adventurer's guild in the Capital. After another five years, the protagonist now in his forties is still acting as a pseudo-adventurer in the countryside, however, his daughter—now a distinguished S-Class adventurer—hasn't returned home even once yet...
