Accounting for even failed runs, if you only run E4 with a level-approppriate team the lowest average per run would be ~300 beads (though if I clear the boss node it's always more than 300 beads). Going from there, in worst case scenario, the total amount of runs on E4 needed for Kogarasumaru would be 200. The luckiest run I had raked in 709 beads, but the run right after the tier 4 Naginata card completely eliminated my team 3 nodes before the boss and I had to come back with only 69 beads. There's also the chance of people abandoning the stage early due to risks, making grinding even quicker.

All in all, you don't have to be /that/ lucky to get Kogarasumaru early. This is actually a very familiar scene in any idol card game; people are persistent and have a lot of cash to spare.
