Kiwame items are available every event, but "easily" depends on your team(s), available time to play, and sometimes how much koban you have. Kotegiri has so far been (mostly) alternating with Tomoe as the big VoT reward, and recently became available from a couple of normal maps.

Assuming you haven't played through any of the maps yet, there's I think 57 free refills left including this evening's. Running the Expert map with an average of 400 beads per run, those free refills would net you 22,800 beads. To get to 80,000 (still assuming 400 beads average) you'd need to refill passes 143 times, which would be 42,900 koban. I think that's right. It should give you an idea of whether or not you have enough koban, at any rate. No need to spend money unless you want to finish the event faster, really.

Also, some of the BGMs are really nice, so if you like having a specific sword as secretary and you like their music, it's worth running the event enough to get the instruments for it.
