Premieres January 12th. The new PV is here. Check out the ANN article for additional information. Synopsis from AniList:
Asagaki Togo was the Red Ranger in a heroic Ranger squad. During their final battle against the ultimate evil organization, he suffers a crushing defeat and resigns himself to death… That is, until he finds himself reborn in an entirely different world! Embracing his new role as an adventurer, he transforms into Kizuna Red and continues his pursuit of justice, helping those in need. Enjoy this heroic tale of a Ranger becoming the protector of another world!
lol. But look! He clearly turns into Voltron!
Green, Yellow, Blue, Pink and Red combine
Red will probably recruit a harem of the usual isekai trope anime girls to become his new ranger squad.
Oh! That makes sense so…
Green obviously has to be the forest elf.
Pink will be the Kingdom’s princess.
Yellow will be a beastman catgirl.
And Blue… a fairy!
