Seriously, How Hard Can It Be? (RWBY - Jacques SI)

Some bloke wakes up as Jacques Schnee. Has no idea what he’s doing and flat-out refuses to learn. Starts winging it with full gaslighting, zero strategy, and the confidence of a man who's never been told “no.” Somehow keeps winning. Somehow makes it everyone else’s problem. A Jacques self-insert with the powers of Potential Man from Jujutsu Kaisen. — Description from novelcodex.org
