Tsunade and Shikako’s relationship is really great! For Shikako Tsunade is the best side of Konoha, and I’m really fascinated by Tsunade’s side even though we see less of it. (I do wonder how much Shikako reminds her of her own teammates, or a best-case scenario version of them…)
Have you read that wonderful recursive about Tsunade comparing Shikako to Orchimaru? I’ll dig it up for you, if not. All the Tsunade POVs are just so wonderful.
