Grandline Shinsekai: Episode 23

Fire with Fire is the twenty-third episode of Grandline Shinsekai.

Plot
At the false site of the summit, the final one on one begins between the Pirates and the Demon Kings. Entei faces off with Baphomet, who claims to be the first son of Appolyon and strongest of all the demon kings. This only excites Entei, who is fired up from the start of their bout.

To begin, most of Entei's attacks appear to be ineffective in the face of Baphomet's "heartbeat". His heartbeat constantly releases shockwaves that protect him from Entei's flames. Baphomet goes on the offensive and quickly overwhelms Entei, using his shockwaves to damage his innards. The demon king claims that his own innards consist of only energy, an energy that constantly grows and must be released through his shockwaves.

On the brink of defeat, Entei thinks back on his father and why he became a Red Wing pirate. This encourages him to get back up and continue fighting Baphoment, although this time, his flames and power increase dramatically. Baphomet attacks, but the flames are able to counter against the power of his shockwaves. Impressed with Entei's second wind, Baphomet enters his full powered form, and the next round of their fight begins.

They trade blows back and forth, both of their powers increasing as the fight goes on. Baphomet starts to recognize Entei's fire as the flames of a dragon, which he describes as flames that can melt anything. Entei's flames start to actually melt through Baphomet's attacks. Through one final struggle, Entei is able to burn away all of Baphomet's internal energy, causing him to desintegrate into ash.
