I'm a Sunman in the World of Chainsaw Man

Chainsaw Man FanSun DevilNo SystemHigh Burn The sun is the origin of life. It is also the oldest natural disaster in civilization. Chen Fan came from a world destroyed by the sun's sudden change, and witnessed oceans boiling, cities melting, and billions of lives reduced to ashes under the scorching sun. When he traveled to the world of "Chainsaw Man", he found that the humans here were in awe of the sun, but had long forgotten their fear of the sun itself. So—— The Sun Demon, born in ancient times and in the same era as the Death Demon, has found the only person in the world who fears the sun. "The ants from another world spread blazing sun and fear for me. In return, I will give you the power of the sun and send you back to before the destruction of the world." The contract is established. Tokyo ushered in an unprecedented "second sun". And an existence that is enough to light up the world and burn it down was born. "Humans..." "Look directly at the sun."
