Luck is the youngest prince of the suspiciously named Social-Game-Loving Kingdom, and he has one goal for his second life: become a royal NEET. After being reincarnated in another world with a special bonus, Luck expects being born into royalty to guarantee him a comfortable life of doing absolutely nothing. Unfortunately, he has arrived in a world where humanity is locked in a dangerous war against the Demon King's army. When Luck turns sixteen and officially gains access to summoning magic, he finally sees a solution. If he can summon an overwhelmingly powerful Hero, someone else can save the world while Luck returns to his peaceful life. Better yet, his summoning circle produces the unmistakable special effect of an SSR-or-higher guaranteed pull.

There's just one problem. Luck cannot summon a normal Hero. Every supposedly ultra-rare summon produces another gorgeous woman with tremendous abilities and an equally tremendous personality problem. His summons include bizarre perverts, troublesome eccentrics, and women whose behavior repeatedly causes scandals that send Luck's reputation as a prince plummeting. Yet despite their strange personalities, the women Luck summons really do possess extraordinary cheat abilities. And although they spend most of their time making his life considerably more difficult, they secretly use those powers to protect both the kingdom and the hapless prince who continues looking after them. Luck keeps pulling the gacha hoping that the next SSR will finally be the proper Hero he needs. Instead, his increasingly ridiculous collection of overpowered problem women just keeps growing.
