* Kanako gives a stray comment on Sugata and Takuto kissing "through glass" in an early episode,
* Wako [[spoiler: has YaoiFangirl ImagineSpot of the two]] in episode 4 and 14.
* In the manga, Ruri sees Takuto and Sugata together and incorrectly assumes they're a "pretty boy couple."
* Takuto also spends every weekend at Sugata's house "so he won't be lonely." [[spoiler:Before his dorm room burns up in the midst of out-of-control fireworks and he has to start living with him.]]
* Takuto and Sugata are seen having baths together three times.
* [[spoiler: Head]] telling [[spoiler: Sugata]] he's happy that "someone as beautiful as him lives on the island"...
** With [[spoiler:Sugata]] coming back to "watch him paint"...
** Episode 14 takes this UpToEleven: [[spoiler: Head tells Sugata that painting what he loves is his idea of happiness. Next, he suggests painting ''a portrait of Sugata''.]]
** Episode 23 isn't even subtle about it: [[spoiler:Sugata receives the painting Head made of him... and Taiga and Jaguar quickly comment that it has an ''unpleasant libido'' on it. Yeah...]]
* Madoka and Kou are basically confirmed as canon.
** And ''then'' it turns out that ''[[spoiler:Kanako]] and [[spoiler:Madoka]] had a relationship together in the past.'' And [[spoiler: Simone]] seems rather jealous to know that.
* Head and [[spoiler:Shingo]] are basically canon, and don't seem shy about expressing it in public.
* Head and Ryousuke also. Ryousuke's the only person still around on the island who cares for Head's well-being, and [[TearJerker misses]] [[spoiler:the Tokio who once picked up a paint brush without being totally consumed by a want for power from the Cybodies]]. Their dynamic seems similar to that of [[spoiler:Sugata and Takuto's]], and seems to be no coincidence that the one to [[spoiler:inspire Head to paint again]] mirrors in temperament and circumstance.
* Kanako and Simone have so many bittersweet vibes going on between them (though one could consider them squicky, due to Simone being [[spoiler: Watanabe's step daughter, servant and classmate. All at once]].
