I Am the Gardener Hero, Summoned from Another World!

You get pulled into another world to fight a demon lord, and the one heroic skill you bring to the job is growing severed heads back to life in a flowerpot. No sword, no magic, just gardening tools and a very strange green thumb. The overview treats this as a punchline, and the game follows suit.

The kingdom still expects a savior, demon lord included, but your only real talent is this flowerpot trick, so the "hero" business becomes less about combat and more about figuring out what a head-growing gardener is actually good for. That answer turns out to involve leverage over the people around you rather than any battlefield glory.

Play centers on working that angle: using your one weird ability to pressure, blackmail, and corrupt your way through the people who stand between you and whatever passes for progress in this kingdom, all filtered through visual novel scenes and choices rather than any gardening minigame. The tone stays crude and joke-forward throughout, so don't expect the story to take its own premise more seriously than it does.
