This is a Ryogoku Alchemi operating night with a clearly posted in-house DJ timetable from 19:00 to 23:30. The event title or theme is not stated, but the rotating schedule makes the DJ component explicit. With four compact slots, it should be easy to catch individual differences from one selector to the next. It reads as a casual stop-in night rather than a heavily branded special event.

ConceptA bar-centered DJ night structured as a four-slot rotation.
