Leonis continues his efforts to rebuild the Dark Lords' Armies to keep his
promise to
Roselia, the Goddess of Rebellion. In the midst of this, he and
the girls of the
eighteenth platoon are busy preparing a cosplay café
for the large-scale school festival
welcoming the Sixth Assault Garden. But
while the festivities heat up, a Dark Lord
buried in ice for countless years
is about to be exhumed!
