Henshin! is a storytelling tabletop game where a group of teens transforms into masked heroes! It is inspired by the Japanese sentai genre, filled with high-energy action sequences and fantastic special effects.


In Henshin!, players narrate episodes about a team of heroes with dual identities and awesome power. Most participants play a Color, a hero designated by archetypes as described in their playbook. One participant is the Narrator, describing the world and all other characters as needed, in addition to guiding each episode through a satisfying arc. You and your friends can play only one episode, or a series of episodes over time that are part of a season.

This game is a love letter to sentai, the pop culture medium of Japanese superheroes. In Japan, these tropes are central to long-running television programs like Super Sentai or Metal Hero, and you may be familiar with North American adaptations like Power Rangers. These live-action shows have teams of color-coded masked heroes using cool suits, weapons, and giant robots to defeat monsters in a display of special effects.

You don’t need to know anything about the sentai genre to start playing. To get a taste of how it all works, visit the Kickstarter campaign and listen to the actual play podcast!
