Sorry I don't follow you ?
There are 14 playable characters announced thus far. 11 of them play the same, whacking at enemies in melee range either with a weapon or close range magic. Rackam and Eugene have rifles and Io has magic and they can manually aim or lock on to targets and shoot from a longer distance away. There's only really two playstyles. I thought it'd be cool if they added more characters who played differently. Having played the gacha, Sara came to mind because of her sand elemental, which could work as a puppet or from Ninja Storm or V's pets from DMCV.
In the Naruto Ninja Storm games, there were puppetmaster characters who played a little unconventionally. They could lock on to a target and send their puppet towards the target, but also be able to move the puppet and/or the puppetmaster character at the same time, and pressing the attack buttons made the puppet attack, not the puppetmaster. But the player retained movement control over both the puppet AND the puppetmaster, so while you were attacking with the puppet, you could move your puppet master around the battlefield to dodge incoming ranged attacks, or move the puppet to block incoming attacks. It's hard to describe, but it was unique and fun and I loved playing as puppetmasters. V from Devil May Cry 5 also plays similarly.
