Episode 7 Story

Gero and Kinosaki are invited to the wedding of the "Bug User," Toshiki Hanamaki. Kinosaki smiles knowingly, noting that "a wedding is a place for new encounters." Also present at the ceremony is Gero’s friend Tsunagi, a "Needle User" and father of three.

While a happy atmosphere fills the air, Yūshū Yamada, who holds a grudge against Hanamaki, arrives with mercenaries to ruin the ceremony. Yamada plots his revenge using the "Five-Point Explosive Fist," a technique utilizing small bombs implanted in his wrists, ankles, and head. To protect his best friend's wedding, Gero teams up with Hanamaki’s partner, Julia Jr. Entrusting the guest-of-honor speech to Kinosaki, Gero leaps into action.

Introduction

Hikaru Gero, a young man inheriting this deadly lineage, has lived his entire life in the underworld, far removed from the touch of romance. To him, the concept of "marriage" was a distant dream. However, to ensure the "Poison User" bloodline survives, the head of the Gero clan issues a cold ultimatum to Hikaru's sister: she will be forced to produce an heir.

Desperate to protect his sister and resolve the succession crisis, Hikaru crosses paths with his latest target—the master marriage swindler, Mei Kinosaki. In a sudden turn of events, Hikaru decides his best option is to get married himself and recruits Mei as his advisor right then and there.

"That’s a first... for a 'proposal,' anyway," Mei remarks.

And so, with a master swindler as his guide, the elite assassin Hikaru embarks on the most difficult mission of his life: Marriage Hunting. Their goal? The perfect marriage. The curtain rises on a world-class, hardcore "marriage-hunting" battle action story, featuring the ultimate buddy duo of an assassin and a con artist!
