It's Tenma's birthday party, and everyone but Karasuma is present. Harima gets interrupted by a phone call during the celebration, saying that Karasuma needs a helper at the Manga office. When Harima gets there, he accidentally spills ink on Karasuma's work, but Karasuma doesn't seem to mind. Harima confronts Karasuma that it's Tenma's birthday, and he should visit as one of Tenma's peers. Karasuma secretly leaves the office to say happy birthday to Tenma, and Harima starts a new layout to make Karasuma's boring Manga piece to look like his own.
