been saving up materials in koihime event for a few days now, haven't bought anything since the first 2-3 days of the event
managed to get mii to 3 star, had more than enough for her 4th but... waited, and just found her in shiny chest!
now.. to wait to find the SR thunder in shiny chest before i'll buy the last copy :P
then i can finally buy the SSR defender wep and use it to upgrade skill level of other weapons ..
