Oh my god, don't tell me that Kizaru will have his guard broken and be sent flying by a base Luffy without even using Haki in his kick? Not to mention that this chapter strongly suggests that Kizaru doesn't have Conqueror's Haki (CoC), since when two individuals with CoC and top-tier strength clash initially, both possessing CoC, Oda depicts them splitting the skies upon first contact. This didn't happen with Garp and Kuzan, Luffy and Kizaru here, but it did happen with Kaido and Big Mom, Shanks and Whitebeard, Roger and Whitebeard, Luffy and Kaido.
