Shiro is going to be Infiltrating as Shokai the Sturgeon Warrior.

Formerly Stricken, but now vaccinated and in remission, Shokai is missing his right arm at the shoulder but is still considered an able warrior and protector. This is a nervous time for him, as he hasn't needed to test how well the vaccine has worked yet. He's a Big Fellow, black tail with white armored points reaching fifteen feet long from his waist to the tip of his caudal fin.

He's a level-headed sort, and strong, set along both for his fighting skills and to serve as pack-fish and possibly babysitter for some of the younger and more rambunctious mermaids. Srs Mission is Srs Bzns. He has a the ability to sense others' electrical signals in the water due to the whisker-like tendrils that sweep back from his temples. He does not, however, have wonderful eyesight. Ten feet distant is about the range of clarity for him and beyond that gets fuzzier and fuzzier. ...he does a lot of squinting.

Weapons: salt-blessed saber at his waist, flint-headed spear across his back
