I'm aware of the lore description, but it's just as stupid as them making Leon's 6P a "1-inch punch" in canon. It defies the very nature of its namesake and is lazily named so that peons could find it in the movelist and know that their BnB combo sequence for nearly every weapon in the game still works with Momiji. Of course it's way weaker so "works" is subjective, but anyway...
