lost_talez's manga / #father daughter(1)

ch22 MC is one of the strongest adventurer/guardian but he was unknowingly afflicted with a curse causing him to lost his HP every time he used his abilities until he only had very little HP left and so kicked out of hero party and eventually loses his adventurer's licence due to failing too many quests. He leaves the city and travels, stumbles on a Fenrir who is actually a little girl under a curse, he tries to cure her but it rebounds on him and thus breaks his own curse. He manages to cure the girl after that and travels with her initially going to leave her with an acquaintance but eventually bonding with her and taking her as his daughter. Alan (hero) found MC's daughter and with help of Edmond (another hero party member) kidnaps her. Edmond threatens hero to take on the curse again as Alan is dying from the curse.
