Hiro Sho

Hiro comes from a species named Sognium Tenebris, also known as Dark Dreams. They're emotionless, androgynous human-shaped beings whose body are made of dark matter. Hiro's parent, Yiro Sho, was considered an anomally, as he developed emotions and thus was considered a threat by his own kind, Leaving Hiro hidden in a dimension where he could be safe from other Tenebris.

Lost, Hiro wandered through dimensions until he ended up in St. Stella City, there he found Shinto, another Tenebris whom he later found out was his brother. While awkward at first, both youths have learnt to see each other as family, despite both struggling to understand how emotions and social connections work.

Despite being an anomaly, Hiro is less expressive than Shinto, often finding it harder to learn more human things. He sometimes helps the small team of heroes his sibling works with while both find a way to keep each other safe from the cult that chases them.
