I am surprised at the number of events that Buchigiri Match is pre-open, but I always think that the number of events will increase, on the event list page in the image above it is clear that all cleared icons are "clear" When the "Complete" icon is displayed, you can tell at a glance if you have any uncleared events...
Of course, if you go to each event page, the number of wins is displayed in the upper left. If the "Battle Start" in the lower center is gray, it means that the event has been completed, but there is a concern that "Is it cleared, isn't it?" .
