Kakenuke★Forward to Our Sparking Youth!

Toono Yuu, a Kazami Academy sophomore, eschews typical teen life for work―― "Youth? No time. I've got jobs." Yuu's all about practicality, choosing part-time jobs over typical teenage fun. He manages his studies well and spends most of his time working for money. His childhood friend Hibiki and classmate Riri, who looks up to Yu, think he needs a change. They each try to get him to join a club. Hibiki champions the "Action Club," nicknamed "Acti-Club"―― lively girls promoting "more youthful fun at school!" Riri advocates the "Volunteer Club," nicknamed "Negati-Club"―― serious girls dedicated to "using youth to better the world." Both relentlessly recruit Yuu―― "Not interested. Don't need youth." Yet Yuu finds himself drawn into their world, despite his protests―― His predictable routine gives way to unexpected experiences. How did this happen? "Isn't it obvious?" his peers suggest. "Brace yourself, senpai. Time to embrace your youth!" What adventures await this reluctant teen!? [Translated from the official site]

The protagonist, Yuu Tono, is a second-year at Kazami Academy. He's at that age that falls right at the apex of one's youth and adolescence. But..."Youth? Who cares about that? I'm busy with my part-time job." He's a hyper-realist who devotes his youth to his part-time job. He adeptly completes his schoolwork while spending every day at work earning money. Hibiki, his childhood friend who refuses to stand by and watch and Riri, a classmate who looks up to Yuu as her master try to get him to join their clubs and change his life. Hibiki encourages him to join the "Activity Collective," or "AcTive" for short, made up of lively girls with the slogan, "Let's enjoy our youth and have tons of fun at school!" Riri encourages him to join the "Volunteer Collective," nicknamed the "NegaTive," made up of diligent girls with the slogan, "Let's devote our precious youths to making the world a better place." Both clubs relentlessly try to recruit Yuu. "I'm not interested in either. Youth isn't essential to me whatsoever." Day after day, the girls refuse to leave Yuu alone, without any concern for what he wants... Why in the world did things turn out this way? "That much oughta be obvious." "Get ready, Senpai. It's high time ya enjoyed your youth!" Just what kind of "youth" awaits Yuu Tono?!
