Ayato figuring out Silas' entire plan of attack (by invoking chess) and crushing it within seconds.
Kirin deciding to break away from her uncle thanks to Ayato and eventually losing to the latter in a duel as part of her first solo action.
Julis and Ayato's first battle of the Phoenix Festa. Calling it a Curb-Stomp battle would be generous and one of the biggest understatements of all-time. Julis doesn't even fight let alone activate her rapier-like Lux; instead leaving it all to Ayato. He releases his limiter, activates Ser-Veresta; crouches down in a stance similar to a sprinter....then he bolts forward as if shot out of a cannon; appears on the other side of the poor enemy saps who's badges he sliced in half. Literally a 'blink and you'll miss it' fight. The commentators (and the crowd) are left utterly speechless.
Ayato and Julis vs Shenyun and Shenhua....most of the fight has the Li twins winning by using misdirection and explosive-invisible-talismans as well as one of the Li twins is cloaked causing all kinds of problems. Ayato then releases one of his limiters and proceeds to completely decimate the twins; all culminating in Ayato splitting a miniature sun in half then flash-stepping to the last twin and clocking him the jaw hard enough to send him flying into the other end of the arena, all while saying; "you did piss me off a little". If that's Ayato only a 'little' pissed off I'd hate to see him enraged.
