Naruto: Unlocking the Power of Death God

"In the 47th year of Konoha, peace is about to arrive. Soul-transmigrated into this world, Hinata Yei, who has experienced the Third Great Ninja War, barely survives the chaos with his 'special' abilities... However, Yei knows that peace is merely a facade; the shadows of war have yet to dissipate... But that’s not the main point. The main point is, Yei wants to know—how to deal with that caged bird hanging over his head, which could take his life at any moment? Should he find the source of the caged bird and resolve it from the root, or should he use abilities from other worlds to seal it? What is the connection between the Reincarnation Eye and the caged bird? There are many questions regarding the system, abilities from other worlds, the power of the Death God, and souls... But Yei is very confident; as long as he is given time, he can figure everything out one by one! 'Who told me I was a cheat character...' Yei said, looking at the pitch-black orb deep within his soul, radiating a faint glow... (PS: The Death God refers to the one from the anime 'Bleach', not others...) (PS2: The main abilities are primarily based on the Kido from the Death God world, mixed with some abilities from other worlds as support...)"
