That's the Mejiro Dober Wit SSR...it doesn't seem very good at all, no, even compared to just the regular good Wit SRs like Daiwa Scarlet, Agnes Tachyon, Marvelous Sunday etc. The only thing it'd be good for is if you want to rack up these event points faster, but most people are focused on trying to breed strong Champions Meet umas right now to do that.
