Guilty!! (ギルティ!!) is a special story included in the Sword Oratoria Volume 8 limited edition booklet.
As the Loki Familia gathered information about the manmade dungeon Knossos, Lefiya was heading over to regroup with the others who had been inquiring from the Amazonesses in what remained of the entertainment district.
As she moved, she caught the backs of a white haired boy and a blond girl walking together, immediately believing that Bell and Ais had been together, again. Stopping in shock, Lefiya quickly became enraged and rushed to berate the boy, forgetting her original goal. Hearing Lefiya, Bell turned around, startled, and while Lefiya began to chastise him, she realized the blond woman was a startled Renard girl, not Ais.
Bell and Haruhime gave Haruhime's introduction to Lefiya, though she was already blushing in shame at her actions. Recognizing her behavior was too much, this time, Lefiya realized that she made the mistaken habit of assuming that white hair walking with blond hair beside it was Bell and Ais.
As Lefiya's panicked thoughts grow more disorderly in her mind, she compared Haruhime's appearance to Ais'. Soon, Lefiya, in her confusion, concluded that Bell was two-timing Ais for another "lovely" and "beautiful" woman. Thoughts completely discordant now, Lefiya shouted at Bell for "cheating" on Ais, while Bell denied having such an intimate relationship with Ais, in the first place.
Lefiya denied Bell's plead of innocence as he was walking with someone other than Ais, an unforgivable act. Bell was shocked, and Haruhime was shyly happy to have the closeness with Bell that Lefiya was claiming. All the while, they were the center of attention for passerby's.
