I wanted to make a kind of fleet girl evolution chat. But while I was drawing this, I thought "Oh, it's Digimon!" and decided to intentionally imitate the digimin style.
Nice finds, a combination with "B" looks and "A" naginata would be amazing for Kaga Tosa Kai Ni.
.P.S.: I can't help but wondering... if the image lets us see that there is a Tosa "perfect" branching path, is there also a corrupted path for the battleship Kaga (aka Ru class Kaga)?
