Shotaro Hidari
is the man of the streets. A self-proclaimed "hard-boiled private eye" who emulates famous pulp fiction private eye characters, dresses himself in 1940s fashion, and possesses a sharp intuition that allows him to deduce the culprit behind a crime before having Philip provide evidence to confirm his suspicions. Vowing to ensure that no one ever feels sad, Shotaro became a protégé of Fuuto's private investigator Sokichi Narumi after crossing paths with him and admiring his work as a child. Unlike his mentor, Shotaro was initially incapable of making tough decisions due to his kindhearted nature making him seek to talk down potentially misguided, redeemable criminals and those in tough straights first; which leads to others viewing him as "half-boiled".

While Shotaro was not originally intended to be partnered with Philip due to his body not bearing the special physiological properties that would make him most ideal to bear the burden of W's powers or resist extranormal Dopant powers possessed by the Museum and Foundation X's executives, Shotaro adapted to the situation through the strength of his resolves, eventually surpassing his physical limitations to unleash W's full abilities and earning the right to wear Sokichi's fedora.

They are also used in W's Maximum Drives. : Grants superhuman athleticism.
