Ansatsusha de Aru Ore no Status ga Yuusha yori mo Akiraka ni Tsuyoi no da ga Episode 1 English Subbed

Oda Akira is the kind of guy who people forget is even there. His unassuming nature pays off, though, when his entire class is swept away to a fantasy world, and he slips easily into his new role as a silent assassin. Between his suspiciously high starting stats and too many details that don't fit, Akira is sure something is wrong. But digging into royal secrets is a dangerous game, and when Akira uncovers an evil scheme, he also makes a powerful enemy—the very king who brought him to this world! With the help of the elven spirit medium Amelia, can he find the power to set things right, and get his revenge? (Source: Seven Seas Entertainment)
