Genma Samonji

Genma Samonji in Onimusha 3: Demon Siege

The Genma Samonji (幻魔 左文字) is the ultimate weapon created by Samanosuke Akechi when he fused the Onimusha Sword with the dark energy that was unleashed from Nobunaga's sword of hatred, the Genma Tenmaji ((減神天魔刃). It has crimson energy surrounding it with an orb of the same color. Samanosuke then used this powerful sword to slay Nobunaga and later sealed his soul. 15 years later in Onimusha: Dawn of DreamsHideyasu Yūki obtains this weapon, where it is known as Gokumonji.
