Sanosuke is too actually can be useful at times. I remember i postponed sophies awakening for 'weeks' because didnt have a single sanosuke. Glad latest events filled my inventory with all sorts of silvers.

Bronzes are too looks like garbage and inv slot wasters but they are actually not. With them i can increase my spirit-tin can usage level limit, thus wasting so less tin-cans and spirit in the end. For instance, i was using them on cc50 plats but i can first level plat to cc57 now with lesser money&fodder spent.
