Over the course of my ~161 E-4 sorties to get Hizamaru, I found 2 Higekiri. Don't use that to calculate drop rates though - eventually I stopped caring about boss rank and so my drop rate almost certainly went down after about the 60th sortie. Still, he's very possible to get! Don't give up!

I felt bad melting down the spare Higekiri. I wish I could give him to one of you who is still struggling. But since I can't, here are some things I noticed.

Switching teams during E-4 is better if you don't have Higekiri yet, because rank on the last battle affects drops. If you use one team all the way through, chances are it'll get heavily damaged and have more trouble getting a good rank on the boss node. At least for me, that was the case, even with my level 99 team of varied sword types... So switching in a fresh one at some point helps.

But, once I got him, I used one team all the way through in order to reduce fatigue buildup and make relatively continuous grinding possible. I will need to retrain myself to retreat immediately when a sword's troops get destroyed or HP becomes too low, now....

Well, I was able to do that because I was lucky enough to have two level 90+ teams that could clear E-4 without retreating. Since my inattentiveness meant each sortie took ~10 minutes - that's just enough time to recover from an average sortie. A mix of oodachi, rarity-3 uchigatana and wakizashi seemed to work the best.

Since the enemy AI pretty much never touches your leader and EXP is bountiful, feel free to set a lower-leveled sword as captain - or at least give your captain(s) ranged troops if possible, since defensive equipment isn't necessary. Horikawa gained at least 15 levels during my grinding.

Well, I don't know if that's useful information at all, but still... Good luck, and have fun!
