i agree with you people, this drawing is really like lulu-heika (whose person say "goodbye" at pixiv before)
i don't know , maybe it's just me but i saw something very strange relation between lulu-heika and this fella who draw this picture. i remember even before lulu-heika say goodbye, this fella here is already exist and also post warship girl just like lulu. Think about it, lulu say goodbye and her account are stagnant but this fella here keep drawing some girls front line picture. isn't that strange but relatable?
