Nice Guy: Before the loops. Still is after them, albeit very broken.
Red Shirt: What he was before spending a year in the loop. note After about 158 loops, each lasting about 30 hours each, he would have spent about 190-195 days or 6.5 months in the loop. He also died in almost all of them. No wonder he was so broken by the end.
Took a Level in Badass: It was long journey but man, DOES he get there. Also a Deconstruction due to how much humanity and things that one care about must be sacrificed in order to become this powerful.
Rita "Valkyrie" Vrataski
The Ace: How she's viewed by the world in general.
Broken Ace: She's just a lonely girl, fighting against a truly horrifying enemy while knowing what they are actually capable of without the ability to share the burden with anyone. Until she meets Keiji.
An Axe to Grind: She is the first user of the Battle Axe on the battlefield and the one who inadvertently passes the skill to Keiji.
Badass Adorable: She's still just a lonely 16/17 year old girl underneath it all.
