The Hunter of Ryujinshima

What if you died and woke up in the world of Hunter x Hunter? For Kess Kobayashi, formerly an ordinary middle-aged man named Anon, this impossible reality unfolds after his first life is cut short. Reborn with an invaluable asset of near-perfect memories from his past life – including an obsessive knowledge of the HxH universe – Kess will take advantage of anything he can to achieve his goal.
