Getter Robo in Heaven's Feel

[No female lead, self-indulgent, most of the plot is pretty much the same as the original, so don't overthink it! That way, it'll be exciting with a touch of tears.]

Jiang Lesheng was an ordinary person. On his way to buy snacks, he dodged a truck, only to be knocked unconscious by a flowerpot dropped from above. When he woke up, he discovered that he had transmigrated into the world of Gurren Lagann.

No need to panic. Let's see what my System gave me first.

What the heck, Getter!

Straight to it!
