Yeah, KBC in World 6 are super easy as long as you're using Tantou/Waki/Uchi. On that note, you could replace Yagen with literally any Uchi—preferably with max stats including HP—give them catapults, and see what happens. They won't get a stat boost but they don't get a penalty, either. The best Uchis would be Izuminokami, Ookurikara, Sengo, or Doudanuki with their high HP, impact and leadership, although they're also much slower than any Tantou or Waki. I'd refrain from using Souza, Mutsunokami, Heshikiri, Yamanbagiri or Kashuu though, since their HP is fairly low and their low leadership means they're less reliable if you want to use catapults.

As for repairing, if you're not comfortable with leaving them in yellow health then there's no getting past constant repairs. Or, well, if you had a lot of Lv50+ Tantous I'd say just switch them out when their health hit orange or red, then put those in for repair and sortie with the undamaged ones. But I think that if they're above 20HP they should be able to take at least 1 more hit before going into red. And even if they go into orange health, they won't break if they're hit as long as you don't continue when they hit red. Yes, you might have to retreat, but you also might not.

We're only 3 days into the month-long anniversary campaign, and Kiwame training is only 4 days so you'd still have lots of time. However, I don't know how much of a difference it'd make, and if you were saving the set for a specific sword you should hold on to it. Might also want to take this opportunity of double EXP to level some other swords as well, so you have more choices for teams.

As for Akashi being impossible to get outside of double drops, he's really not. While it took me a while to get him the first time, I have since gotten him at least half a dozen other times just by running the map for EXP and KBC hunts, all of those times outside of double drop campaigns.
