Ultra: Super Ancient Trash Fish? I Save the World!

(No cp + no heroine + time travel + cool writing + slow pace but never boring + not brainless) Don't cross the border, you will become unlucky. Especially when he turns into a super-ancient giant who is 56 meters tall, weighs 48,000 tons, and can blow up a mountain with one punch... Thirty million years ago, while resisting the four dark giants, I ran out of energy and turned into a stone statue. Thirty million years later, I woke up in worlds on the verge of destruction one after another. In Devilman, people are desperate in the attack of demons, and a ray of light shatters Satan's dream of world destruction. Among the giants, when the giant's footsteps crush freedom, I use my iron fist to end the century-old tragedy; Facing the magical girl, when the girl's prayer turned into a curse, I used a miracle to cut off the fate of despair. Me: "I'm such a jerk." Villains from all over the world: "Please stop showing off! Our world view has been crushed by you!!!"
