I've been wanting to mod 9S in some way into the game and saw somebody wanting it on Mika. I suppose it's because Mika is good support for the upcoming 3.8 with Eula the same way 9S acts as a support for A2.
This includes a full/half/and none toggle for the fundoshi, an on/off toggle for a ring, as well as the cape toggle mentioned before :D! (Toggles for the early access are the "5" for the Cape, "6" for the Fundoshi, and "7" for the Ring)
