Sometimes Honkai's lack of threat is evident when the Valkyries just have fun and hang out at the Schicksal HQs, letting it be seen that they are still normal humans after all.

There wasn't a day that went by when something didn't happen that was a future anecdote, this was clear when Seele and her friends were teasing (in a friendly way) Veliona about who she liked... and what a taste she has.

"Seele, shut up. I won't let you tell the Captain I like him, I swear if you tell him I– C-captain?"

The "mercyless" Valkyrie couldn't even avoid blushing when she realized you were behind her; she wanted to die inside but at the same time she didn't seem to try to deny it, after all she's still the mature one of the group and she can't feel ashamed for her feelings.
