Argento Soma

A laboratory catastrophe kills Takuto Kaneshiro's girlfriend and leaves him physically scarred. He blames the revived alien called Frank, and accepts a new identity as Ryu Soma to enter FUNERAL, the organization that now uses the creature against other alien threats.

Revenge becomes less straightforward when Ryu sees Frank's bond with the orphan Harriet. Working beside the being he hates, he encounters questions the military cannot answer about the invaders and himself. Each battle brings him closer to his target, while making his certainty about that target harder to preserve.
