Fire Emblem Fates Birthright - Kagero "Solo" - Chapter 18

Provided you don't skip it by immediately killing Leo with the Beast Killer, Chapter 18 is what I see as one of the game's three mandatory grind maps in a more casual playthrough. Even when I'm playing this casually, I use this map to build weapon ranks and supports, though in a solo run it's pretty useful for gaining EXP, too, even if Kagero and Corrin are only getting one per kill. Corrin is a Great Knight because I wanted her to get Elbow Room, though she didn't here. Kagero got Vantage and Seal Strength, though. She also reached D-rank in lances.
You know something is concerning when my biggest concern every time I play this chapter is accidentally killing the boss before every other enemy dies. Funnily enough, despite being a Level 12 Dark Knight, he actually has lower base magic than when he joins in Conquest despite being Level 2. Granted, Kagero is still in Master of Arms and therefore only really has access to the Kodachi (and Javelin but I don't use it), so I don't have to worry about immediately killing him if he so much as looks at her. I also managed to kill the faceless before Turn 13 where Leo and his retainers start moving. They, too, are also rather weak and easy to kill even on a casual playthrough. At least the Silver Yumi is free money. In this playthrough, the same goes for the Horse Spirit, though it would be more valuable if I were using a magic unit like Orochi or Anna.
Speaking of Orochi, Kagero's support with her reached B, and her support with Corrin reached A.
