あるけみ祭り

At Alchemisuto, the evening starts with a timed rotation from 19:00, then shifts into Alchemi Festival from midnight. Yusuke, Kyube, Ryuta, and Haruto are each assigned their own slots, which suggests a gradual build before the overnight portion takes over. The venue explicitly says the event runs until morning, so this reads as a stay-late kind of night rather than a quick stop. It should appeal to people who enjoy intimate Akihabara nightlife with a homemade atmosphere.

ConceptA local night that transitions from early slots into a proper overnight session.
