Warning: Spoilers for the raw, unedited Japanese text of Chapter 154 follow.
If you are just catching up, the premise is deceptively simple. Rakuro is a "Shitty Game Hunter"—a player who dedicates his life to clearing broken, buggy, unfair "kusoge" (shitty games). He does this to sharpen his reflexes and test his limits. When he decides to play Shangri-La Frontier , a "kamige" (godly game) with perfect balance and design, he brings that same chaotic, exploit-heavy mindset to a polished world.
: By leveraging these non-traditional mechanics, Kei manages to take the first round, leaving Sylvia to figure out a counter-strategy for the next round. Series Context
