In Tiga: Transforming into Gaia to Save the World

[Tiga, everyday life, hilarious, heartwarming, lighthearted, Gaia]

Gakuma gets killed? Not on my watch.

Machina gets beaten up? Absolutely not.

Obik wants to die? I won't allow it.

Silla...

The protagonist drowned while saving an elderly woman who had fallen into the water. By a twist of fate, he transmigrated to the world of Tiga. The ridiculous part was that he happened to have a Gaia transformation device, with the King of Ultra having stored Gaia's power inside it. From then on, the protagonist would transform into Gaia and change the fates of countless monsters!
