As the seasons turn, Rimuru plans a Bon Festival celebration. Each race has its own history, and the festival is a time to show gratitude and reaffirm their bonds among their own families and clans, and to strengthen friendships by telling others all about their own histories. And with this Bon Festival, Shizu-san returns to Tempest as a spirit...
Actually, she was in the form of 
a bunny being chased by monsters.
في الواقع، كانَتْ على هيئةِ أرنب
يُطارَد بواسطة وحوش
Sie hatte ein Hasenkostüm an
und wurde von Dämonen verfolgt.
Na verdade, ela estava vestida de coelhinha
e sendo perseguida por monstros!
Не поверишь! За ней в костюме зайчика
бегали магвери!
