Reishi (霊視 , lit. "Spirit Reading") is a supernatural ability to read the minds and hearts of others[1] and is akin to shamans' ability to see spirits.[2]
About[]
Though it was quite a useful ability, constantly being inundated with the thoughts of others, especially their negative emotions, can lead to instability and an inability to control one's own feelings. This lack of control can spawn oni from the user's Furyoku.[1][3]
According to Asakura Hao, the ability derives from a strong sense of loneliness.[2] As such, if the user lets go of their rage and sorrow and surrounds themselves in kindness, they lose the ability to read minds.[4]
