Kairi and Astolfo helping Mordred to refill her mana - with double the efficiency!
I never let go all that mana transfer thing since Rin and Emiya had "that scene" at that time when Fate was a little visual novel with, ahem, some classic visual novel elements.
Its fun to think how Mordred or Astolfo would react to a suggestion of some good ol' "mana transfer" between master and servant.
It's all fun and games until your servant is Heracles or Spartacus and its time to transfer some mana💀
Jokes aside, Mordred is the best girl ♥ She's the barometer I use to "how tomboyish" a waifu is, I'm waiting for the time once Hoyo releases a character as close as her personality and visuals-wise. >﹏<
