Awesome Music: The music is composed by Elements Garden, and some of the tracks definitely apply, like "CRYSTAL TIME".
Big Lipped Alligator Moment: Cecil's appereance in the first season. Only Haruka meets him, and he's never mentioned again until he comes back to join the Master Course in the second.
Also happens in the main game's routes (except his own): he appears suddenly to give some advice to Haruka, and later dissapears for the rest of the route with no explanation.
The second season's ending. Everyone floating in the sky and reaching space.
Broken Base: For some fans of the original game the anime dumbifies the characters and loses the spirit of the original. However, there are also many fans who knew the franchise thanks to the animated series, and who prefer watching the guys interacting with each other than engaging in romance with Haruka.
The use of CG in "Maji Love Revolutions". Some find it cheap, others don't mind and consider it makes the song different to the previous endings.
The focus of the anime being given to HEAVENS.
Die for Our Ship: Haruka is a girl in an otome game. Three guesses as to what the rabid yaoi fans do to her.
Out of the main six guys Natsuki seems to be the most popular, if fanart is any indication.
Out of the senpais, Ranmaru and Ai for game fans. Although Reiji became more popular between anime fans after his central episode in Revolutions.
In the 2015 "Top 20 Characters Otaku Want to Marry" in the "Ideal Husband" category, Syo placed third overall, placing the highest out of all the Uta no Prince-Sama characters, and was below Makoto from Free and Arakita from Yowamushi Pedal.
Ethnic Scrappy: How some fans see Cecil and (to a lesser extent) Camus.
Launcher of a Thousand Ships: Haruka. Considering she's the heroine of an otome game, she already has at least six good-looking guys after her; she can be paired with Otoya, Tokiya, Masato, Ren, Syo, Natsuki, Cecil, Hyuuga, Ringo, Reiji, Ranmaru, Camus, Ai... and the list goes on.
Les Yay: Haruka gets REALLY happy when Tomochika visits her.
One-Hit Wonder: In universe, Shining Saotome. He had one best-selling single, "Wo Ai ni", before retiring and funding Saotome Productions and the academy.
The Scrappy: Haruka, for fans of the anime (mainly disliked for her generic personality) and Cecil for both game and anime fandoms.
The leader of Heavens as soon as his group appeared.
They Just Didn't Care: The anime is notable for barely adapting the source material, but they've gone too far with the third season, with many moments out of character (namely the senpais) and Off Model shots.
