My beloved partner was recruited into the Hero's party, and we were separated.

For three years after that, I desperately continued to support the Hero's party from afar, even rising to the rank of an S-rank adventurer.

Yet, when I finally reunited with my partner, they were having an affair with the Hero――

"Since things have come to this, and I couldn't even thank you... at least, I want to return the sword."

S-rank adventurer "Four Swords" Abel Sixam, having lost the meaning of living with his partner, embarks on a journey to return his signature demonic sword to the one who entrusted it to him.

――Little did he know that along the way, he would become entangled with beautiful women he encountered, and through them, be made to understand his past actions and the true meaning of his life.

Meanwhile, his ex-partner desperately tries to win him back, but is completely blocked by the beautiful women.

Forced to watch, they both, along with the Hero, descend into days of hell.
