The upcoming fight is a question mark for me because we know nothing about Boro and our heroes could very likely be walking into a trap. Kawaki may be the strongest of the group if he can maintain his transformation long enough. Mitsuki has sage transformation but its also questionable if he can maintain it long enough to defeat an inner of Kara. Boruto doesn't know how to use his karma seal and Sarada really has nothing to contribute with her current skillset. Taking those things into consideration I do not believe they will win this fight. This was a battle meant for Sasuke Uchiha but he isn't capable of fighting in his current state.
