- "Mercy? I have none!"
- — Mitsurugi
Heishiro Mitsurugi (御剣 平四郎, Mitsurugi Heishirō) is a character in the Soul series of fighting games. He appeared in the game Soulcalibur VI, which marks his debut appearance in the new, rebooted Soulcalibur timeline. The exact English translation of his nickname, Mercenary in the Warlike Age (戦国の用心棒 Sengoku no yōjinbō?), is unknown.
In response to the appearance of the firearms on the battlefield, Mitsurugi began a search for a formidable weapon to help turn the tide of the changing times. After facing defeat in a Tanegashima tournament, Mitsurugi begins training diligently in hopes to become a more refined warrior. During one of his traning sessions, a Village Merchant approaches him and tells him of a powerful warrior named Nightmare who is wrecking havoc on the countryside with an invincible sword. Mitsurugi vows to find Soul Edge and crosses into the Chinese mainland.
After overwhelming a group of ruffians, Mitsurugi continued to head west to Europe, fighting new challenges along the way. After defeating a wandering Samurai, Misturugi meets Edge Master who compliments his fierce fighting capabilities. The two strike up a friendship and begin to journey together. The two of them discuss martial art techniques regularly while drinking together. Edge Master confirms he is aware of Nightmare but is sparse with details. Edge Master urges Mitsurugi to continue to fight to help 'jog his memory'. Mitsurugi continues to defeat stronger and stronger foes on his journey. Mitsurugi wishes to fight Edge Master but the old man refuses.
Edge Master leads Mitsurugi and disappears shortly after. Taki appears before Mitsurugi that two fight before Taki admits to Mitsurugi being duped. Edge Master leaves Mitsurugi a note, telling him that he could not allow Mitsurugi to get to Soul Edge for his own protection. Mitsurugi vows to do battle against Edge Master the next time the two may meet.
Mitsurugi calls his style Tenpu-Kosai-Ryu. Unlike most fighters of a new style, he has no desire to open a school and gather disciples to pass it on to. Rather, it is likely that he uses his skills simply as means to help his services as a mercenary.
Thunderbolt Blade: Slashes his opponent which lifts them up into the air, then strikes them down with another slash which launches them higher into the air.
