That names gonna be Yuzuru. If you look here ( https://japanese-names.info/first_name/yuzuru/ ) theres a lot of meaning depending on how you write yuzuru in japanese. Theres "lapiz luzuli" the jewel , theres also "escape" , also "to help"

From my speculations and other comment that what i think the skills are

He'll become a puddle of ferrofluid and able to roam freely for a couple of seconds same as reynas invi but you can see a trail.

His ult activates his ferrofluid to take form of a samurai armor. If you would look at the silhouette image with the new agent in the middle. Look at the left shoulder you can see some kind of shoulder pad.

Not sure about the other skills though. I was thinking of a throwable proximity knife or shuriken or kunain or even flying paper bombs that you can activate to self destruct
