Shigen Naoe/Story

Shigen is a guardian of a portal called the “Hell’s Gate”. Before the events of the first game, he is magically sealed in a massive stone for ten years by his friend Shinnosuke Kagami who perceived him to be a threat in his plan for opening the Hell's Gate. He eventually escaped, but clouded by his rage and anger, he could only think of getting back at his captor. He set out to exact revenge.

By the events of The Last Blade 2, Shigen had regained his senses and remembered that he had a daughter. To atone for his ten year absence, he traveled to the mountains to spend time with her while training. During this timeframe, he noticed the evil aura that emanated from the opened “Hell’s Gate”. As one of its guardians, he set out to close it, leaving his sleeping daughter in the darkness of night. However, he was initially unaware that his daughter knew of his departure and that she was following him at a distance.

Shigen, along with Yuki, Gaisei, and Zantetsu are the only known characters to die after the events of The Last Blade 2. Shigen died of overexhaustion due to his powers as the avatar of Byakkko. Afterwards, it is implied Kagami ended up adopting and raising his daughter in his place; his daughter likewise took up his mantle and becomes Byakko's avatar herself, taking Byakko's rosary and wearing it around her neck.
