Red Fang: Blue Sonnet

Sonnet, a hardened cyborg-esper trained to become the world’s most lethal weapon, is sent to Japan to monitor Komatsuzaki Lan-a reserved girl who senses she isn’t like others. Lan begins exhibiting the influence of the esper Akai Kiba ("Crimson Fang") after encountering Sonnet. As they clash, Sonnet gradually reconnects with her own humanity, while Lan struggles to maintain control over herself and resist Crimson Fang’s fury.
