Kagutsuchi Port is a stage located at a magic ship port in upper Kagutsuchi. It has three different versions, each representing a different time of day, which can be read on the large clock in the background.
The 10:30 version has various passerby in the background, including some beastman. A Control Organization airship is docked in the port. As the match continues, the ship slowly embarks.
The 9:00 version takes place at night, with different background characters, including a guitar player (whose strumming can be heard during the match and during the introduction sequence) and a goat-like beastman who walks in from the right side of the stage.
The 4:45 PM version begins with a rainstorm that subsides, leaving puddles on the ground. Afterwards, the background features a cloudy sunset. This version has no background characters.
The clock in the 16:45 version reads 17:30 (5:30 PM) instead.
In BlazBlue: Chronophantasma, the 16:45 pm version has been renamed to 4:45 pm.
