Steel of the Celestial Shadows Vol 4 4

A down-and-out samurai named Ryudo Konosuke struggles through his hardscrabble life in early 19th-century Japan. It is said that a samurai's spirit rests in their sword--and Konosuke can't even pick one up thanks to a cruel curse that repels anything made of metal that gets near him. Destitute and hopeless, he decides to end it all. But when a beautiful and mysterious woman saves his life and his soul, it is the beginning of Konosuke's journey into a strange world of magic that exists a step away from his own.

Down-and-out samurai Ryudo Konosuke has a supernatural gift, but it is a power that has ruined his life. For the gifted, their abilities can be a double-edged sword, granting amazing abilities yet threatening to overwhelm them at the same time. After escaping from some assassins, Konosuke and Aki both struggle not to lose themselves to their gifts. Then a new ally relates the secret story of Lord Haretake of the Tsuchimikado clan. Konosuke will stop at nothing to find his love, Tsuki, but Lord Haretake needs her divine power for his own dark plans...
