Mizu Zokusei no Mahoutsukai

Synopsis:

After being reborn in a fantasy world, Ryo hopes for a quiet life using his limited water magic—he can only summon a cup at a time, but it's enough for a modest, peaceful existence. Or so he believes. Instead, he's dropped into a remote, monster-infested wilderness with just a small shack, a knife, some provisions, and magical powers he doesn’t yet understand. With no other humans around, survival becomes his top priority. Undeterred, Ryo is prepared to face down wild beasts and terrifying creatures alike in pursuit of the life he dreams of. Every hard-won victory brings tougher trials, and soon Ryo crosses paths with a headless horseman, a dragon, and a stranded swordsman—encounters that set him on an epic journey. Step by step, he ventures far beyond the world he once knew, chasing his destiny to become the greatest water mage of all time.
