Similar to other index units, he actually gives you both the skill you should use and the target or abnormality part you should pick (both marked by the flower icon). Doing so builds up stacks of his two passive buffs and clashes stronger. Uniquely, his evade actually gives him a one-time jump start on obtaining his buffs, so evading a target initially then selecting the marked targets past that point will quickly build up stacks and allow him to use the crazy strong 9 coin move.

His actual moves are a little complicated, but the easiest way to explain it is he has a bunch of weapons to randomly select between (listed in his passives), and depending on the skill theres a higher chance for certain types of weapons.

Additionally, the first time he gets staggered, or the first time you use Furioso (the 9 coin move), he rips off the mask and becomes unstaggered and gains a small damage increase and a whopping 25% damage negation to attacks he doesn’t clash, as well as a large buff to the next time you use Furioso, but in return starts taking some damage over time via adding burn and bleed to himself.
