Gang Tu-Ji is just a normal passionate and determined (pun intended) 13 year old boy trying to woo the prettiest girl in school. That is until 4 mysterious creatures crash through his roof one day. Tu-Ji ends up reluctantly helping them out by transforming into Tribe Captain via the Giga Stone's power they brought. And the creatures themselves are able to morph into fully humanoid super sentai-like warriors! Together they fight against friends and strangers who have been possessed by the evil Bavaria in a catch-phrase sitcom manner.
