History Characters / MermaidMelodyPichiPichiPitchHumans

* AdaptationRelationshipOverhaul: The original manga's version of Kaito and Lucia's relationship is less about the LovesMyAlterEgo situation it's played as in the anime (in fact, in the manga, Kaito has suspicions Lucia might be the mermaid from the very beginning) and more about the fact Kaito's inability to ''commit'' to Lucia as long as he's hung up about the mermaid, while Lucia won't open up to him fully about her problems due to TheMasquerade. About halfway into the first arc, Kaito decides to stop beating around the bush and properly commit to Lucia because she's the one who's regularly in his life; him learning that she and the mermaid are the same person mostly serves to give Kaito closure about the issue and allow Lucia to be more open with him.

* UnevenHybrid: [[spoiler:There's a mermaid somewhere in his ancestry. This is never approached in the anime]].

* AdaptationRelationshipOverhaul: The original manga's version of Kaito and Lucia's relationship is less about a LovesMyAlterEgo situation (in fact, Kaito has suspicions Lucia might be the mermaid from the very beginning) and more about the fact that, as much as Kaito likes Lucia and constantly flirts with her, he can't ''commit'' to her as long as he's hung up about the mermaid, and meanwhile Lucia can't fully confide things in him because of the need to uphold TheMasquerade. About halfway into the first arc, Kaito decides to stop beating around the bush and properly commit to Lucia because she's the one who's regularly in his life; him learning that she and the mermaid are the same person mostly serves to give Kaito closure about the issue and allow Lucia to be more open with him. The anime's version is much more ambiguous on Kaito's feelings on Lucia and has him still be pining for the mermaid until the very end of the first series, and he's much more unaware of the idea they're the same person until then, making it more of a traditional TwoPersonLoveTriangle setup.
** Likewise, the anime plays the issue of Kaito and Michal as more of a LoveTriangle than the manga does, where it's much clearer that Kaito doesn't have any romantic interest in Michal whatsoever but is staying with her out of compassion and a sense of duty (especially because she'll do things like ''threaten suicide'' if he attempts to leave), whereas he's still clearly interested in Lucia despite having lost his memories of her. Lucia herself is aware of this; it's just that it doesn't stop her from feeling lonely about it anyway. The EasyAmnesia part also drops out of the narrative much earlier than it does in the anime, making Kaito and Lucia's relationship concerns more about the latter's frustration at ''still'' being LockedOutOfTheLoop in regards to his problems than it is about a question of them being together.

* TheScrappy: Mikaru is extremely despised by fans for her jealousy over Luchia, other reasons why she is hated are for her feigning her illnesses just for the sake of Kaito getting her attention, for her being ungrateful towards her brother Rihito who devoted his whole life to make her life better, and for taking Kaito's personal space.
