Sentai Red Isekai de Boukensha ni Naru

Both MCs have unexpected abilities that defy the laws of their fantasy world. They both end up forming parties with Princesses who are accompanied by strong swordsmen.  

Both MCs are Power Rangers in Anime form so they look slightly different but contain all the wacky essence of a typical Power Ranger. Although one infiltrates the Rangers to destroy them the other is hell bent on saving this new fantasy world from evil so he can go back to his own world! 

Both MCs are knock off Power Rangers fighting against the evils of their worlds. Little do they know love also seems to be on the horizon!  

Both are heavry inspired by the Tokusatsu show and do a great job capture the feeling of toku show highly recommend if you are Super Sentai / Kamen Rider / Ultraman fans
