One of my favorite Sailor Moon episodes is on PlutoTV right now - where Minako’s hung up on being the only senshi who hasn’t had her Pure Heart Crystal stolen and tries to prove how PURE REALLY PURE SEE HOW PURE IT IS her heart is. Such a great mix of slapstick comedy, sentimentality, action, and Girl Power(TM).
(It’s also the episode where the Inner and Outer Senshi learn each other’s identities, but that’s not, like, important or anything.)
