Trivia

 * Oni-Chan (鬼) refers to a kind yōkai, demon, troll in Japanese folklore. But this can be misinterpreted as Oniichan (お兄ちゃん) which refers to an older brother.
 * This is the fourth time Kagami has been akumatized, following "Riposte" and twice in "Mayura."
 * However, unlike her previous akumatizations, Kagami doesn't get akumatized into Riposte, but instead into a new villain, Onichan.
 * This makes her the fifth character to be akumatized into a new akumatized identity, followed by Chloé Bourgeois (Queen Wasp), Lila Rossi (Chameleon), Nino Lahiffe (Shell Shock, Oblivio) and Alya Césaire (Rena Rage, Oblivio).
 * This is the second time Ladybug has her Lucky Charm taken away following "Robostus".
 * A flashback to "Frozer" is seen.
 * Gabriel and Lila make an official alliance, despite the latter not knowing that he is Hawk Moth.
 * This is the third time that Ladybug and Cat Noir don't do their "pound it" fistbump after "The Collector" and "Anansi".
 * Lila's horn growing bigger every time she lied is a reference to "Pinocchio".
 * This episode reveals that Kagami has a crush on Adrien.
 * This is the second episode where Cat Noir's transformation sequence is shown but not Ladybug's.

Errors

 * Lila's bag is white instead of red.
