Most likely! The problem with the clones is that Shima without his familiar is basically just a decently trained teenage boy. He's got the addition of a few annoying powers but they're not particularly offensive and the element of surprise is likely already wearing off. Getting kicked around by a full grown lion is actually A Lot for a human.

Unluckily for Shura, there are also a lot of Shimas. A few more notice that some are tangling with someone that is definitely a threat if left alone and come to join the fight.
