Isshun de Chiryou shiteita noni Yakutatazu to Tsuihou sareta Tensai Chiyushi, Yami Healer toshite Tanoshiku Ikiru

Zenos taught himself healing because poverty and status kept him from the official licensing system, then spent years being exploited by an adventuring party that eventually discarded him as useless. Rather than collapse, he decides to use his exceptional ability on his own terms and opens an unlicensed clinic in the shadows, serving people legitimate healers would rather ignore.

With the elf girl Lily beside him, Zenos treats everyone from gang members to rival races caught in violent disputes, often ending conflicts simply because he is the only person willing and able to save every side. The underground healer's success soon reaches the ears of knights and authorities who do not appreciate an unlicensed miracle worker operating beyond their control. The wider his reputation spreads, the harder it becomes to protect both his clinic and the principles behind it.
