Context: During FGO FES 2025, in Club Chaldea Satellite Station Day 2 during the panel with Ookubo Rumi and Kawanishi Kengo (Miyamoto Iori's voice actor), Kawanishi addressed Yamato Takeru as うちのセイバー (my Saber) several times. He later stated that calling them "Saber" feels just right (instead of calling them Takeru).
I've heard a lot of things, but first of all...!!You referred to me as "my Saber"? Just what do you mean by that!?I'm not anyone's belonging, you know! I know you're not....You don't seem to understand how misleading that could be. sigh...That's not true at all....Even I received basic education back when I was alive.And now I have the Holy Grail's blessing as well.Hm?I said that with a full understanding of what it meant.Then it's fine.Mmmh...
