Shinohara Kokonotsu

42-year-old Suzuki Takashi is a former hitman and mercenary. Although he died of cancer, he was reincarnated into another world due to his potential as an assassin. He uses the modern combat techniques he developed in his previous life, the ancient martial art Shingu-ryu and his newly acquired powerful magic to face off against the unrivaled heroes.

In a world where deceased people turn into stone-like books and are stored in the Bantorra Library, anyone who reads a book can learn its past. Bantorra Library is maintained by the Armed Librarians, who wield supernatural abilities, and their enemy is a psychotic cult known as Shindeki Church. As the story progresses it presents a world of sorrow and pain, and the unfairness and frugality of life, as well as personal desires. However, in each arc there is also a small underlying hope, and more of the reasons, conspiracies, and secrets are revealed behind everything. It is about a specific overall history in time of Bantorra Library and its people. Each character dies a sorrowful yet meaningful death, and each death will open paths to a small ray of hope in the world, which also reveals a part of a secret to the reader.
