Also his twin guns are named Stormflower. Nora's Magnhild if you translate the first part of the name, Magn, it means strong, mighty, strength. Aka POWA~! So he took the flower of Ren's weapon and the power of Nora's. Flower Power. I actually think Arkos (besides the shipping name) fits in that as well. Crocea Mors and Milo(Spear rifle) and Akoúo̱ (shield). Arkos seems like The Mors and Akoúo̱ put together. He did say something about the shields being put together in a certain way before the other team interrupted.
