Araki Yuusuke

Aika Tendou has given up Vanguard to protect his younger sister Rino, whose overwhelming imagination once made a cardfight feel real—and left her unconscious for a week. Their quiet life is shaken by transfer student Sekai Mase, who seems mysteriously connected to Rino and her paintings. This manga is based on a fan-submitted storyboard from Monthly Bushiroad's Vanguard Manga Award contest.

High-rank parties chasing out their own party members because of their low stats has recently become a common trend. A young man named Aizen, feeling dissatisfied about the current status supremacism, has decided to gather the outcasts who were expelled due their low stats, and establish his own guild together with them. "Are you kicking them out of your party? I'm going to recruit them then!" A person's abilities isn't limited to their stats alone. The "weak" will bloom and become "strong" using of their latent abilities, their "hidden skill"!

I’m good at support roles, can I join your party?" Ragdishart, a young explorer, has the ability "Enhancer": an ability only chosen by 1 in 100, and is infamously considered the weakest ability ever. No-one would let him in their party, but little do they know, he holds a second, more powerful ability. "Multitasking", which means he can simultaneously control 10 or more arts. Requiring superhuman concentration ability, it takes him only 3 minutes to be able to strengthen his physical ability 1024-fold. Hence, Ragdishart is both the “weakest” and “strongest”. In his adventures, he travels to a ruined tower that extends to the moon, called “Lunatic Babel”. When a human boy meets a deity girl, the story begins.
