Conquer The Ninja World by Akito B. Takahashi (Paperback)

Eight months have passed, and Jonathan Yuan is still in the world of ninjas. Plans falling apart, many of his adversaries gradually start to learn of his identity. However, he has no thoughts of going back on his actions. After being stagnant about slaying everything in this world, he continues to try and grow as fast and as strong as he possibly can.

"Being a classic read, the Conquer the Ninja World series never fails to impress. Its main character continues to endure this mysterious version of hell, always staying faithful in Jesus Christ as his Lord and Saviour, even when all hope seems lost."
