"With this system, I'll become the world's greatest seducer! If it doesn't kill me first..." I was a nobody, a short fatty Otaku. Then a girl's voice popped into my head: [Seduce a woman within a month or die.]
"What the hell...how? I'm an 18-year-old virgin..."
[7+ looks only. No slam donkeys.]
"You’re forcing me to die!”

Facing annihilation, I had no choice but to join the international community of pick up artists. That’s how my boring student life became filled with craziness and womanizing. I just had one problem: "Why are these guys all insane?"

Pick Up Artist: One who uses specialized tactics to seduce women.

Summoning ceremonies can freely call forth even “those which lurk in the depths beyond the gods”. One boy has top-level abilities even among the cutting-edge summoners who can use those ceremonies. He is Alice (with) Rabbit aka Shiroyama Kyousuke. But this strongest boy summoner has a single fatal weakness. Certain “cursed words” spoken by girls: “Help me.”

When Kyousuke hears those words from Meinokawa Higan, a girl brought to the verge of death, he throws himself into a city where three great summoner forces clash!
