Inter-dimensional Supporter IDS

A zombie liked man in rugged clothing climb outs of a pile of debris.
“Oh, it a good thing I manage to dodge the attack or else terrible consequences will occur”
He wipe away his dust filled face and look ahead. A colossus shadow loom over him covering his surrounding. Out appeared a giant metal colossi that is 80 meters tall emitting an oppressive aura. Electric spark and fiery red glow emanate from it eyes.
”Why won't you die already!!”

Come journey into a world where the main character is personally weak on his own but get stronger with allies and companion.

This is a passion project started because I feel like the MVP of many novel isn’t an support character. There already a novel with the Mc of being a healer but wait this is a novel involving other works of fiction mostly anime and other novels.

(This is honestly the first novel I wrote so and criticism would be appreciated. I don't know if I should include this or not but English isn't really my main language and biggest thanks go to Grammarly.)
