"Sukimas" are interlude stories between chapters, published at the end for the volumes of the Mairimashita! Iruma-kun manga. Those stories were adapted into little segments playing after the ending credits of the Welcome to Demon School! Iruma-kun anime's episodes.
Manga[]
The stories usually come under the form of a column of four panels and in pairs of two but not all the times. They mostly expands on the scenes from the manga with little funny moments where the quirks of each characters go off the rails. However sometimes there is also some slice of life stories about the author where she is represented as a fluffy cat in a zoomorphic world.
Anime[]
The stories are adapted in a different aesthetic style than the episodes. The overall style seems more simplistic like drawings in bright colors echoing the shades of pastel colors. It looks like the idea here is to show a world seen through the eyes of a little child, the characters themselves often looking like little children.
Title of the Sukima Segment[]
The title's segment changes a little bit with each episodes. Mostly by Clara announcing it in a different manner, except when other characters replaced her from time to time especially during episodes of the Harvest Festival.
