Supergod Fusion: I Merge with Beasts to Save Humanity!

When corrupted beasts threaten to end civilization, one warrior discovers the ultimate power—fusion. Armed with stolen gene sequences from the monstrous Brahma beasts, he transforms into humanity's last hope. As the Karma Demon descends and the Savior unsheathes his blade, every battle reshapes the future. His sword ignites flames that will either illuminate mankind's survival or burn away its final chance.
