Umbra.

In Sense Life, Umbra is a character whose main ability is Mind Reading, allowing him to incessantly access the complete memories of anyone he touches, from birth to the present moment, functioning like "high-speed book reading." His powers originate from being a Tribute (a superpower granted through emotional bonds with the deceased), and he uses this ability for investigations, being a "Tribute User" with genius-level intelligence.

Umbra's personality in Sense Life is that of an extremely intelligent and calculating individual, focused on investigation, who uses his ability to access memories (The Eyes of the Other) to extract information from other tribute users, acting strategically and with in-depth knowledge of others' abilities, unlike Noah's apathy.
