Place it right after the reveal in an edit, once the odd pick is on screen. Open with Enemy Spotted to build suspicion, let this clip deliver the answer, then cut to Okay Let's Go as the group moves on to the next round.
このサウンドについて
This is a 2.6-second Russian voice clip built around the line about a banana and Soraka, delivered as a quick, deadpan-sounding remark. The mismatch between the ordinary fruit and the champion's name makes it feel absurd and lightly teasing, like an inside joke landing in the middle of a game. It works best as a short reaction rather than a statement on its own.
