Between February 19 and March 5, 2019, there was a museum for the
TV anime Wataten, Watashi ni Tenshi ga Maiorita (私に天使が舞い降りた),
on the 7th floor of Gamers.
There were some character pops, anime panels, other artwork,
and some signed goods, but photos weren't allowed of anything
except for the character pops.
