* {{Adorkable}}: Akihito's plucky and energetic personality naturally causes him to be endearing to the viewers.
* AlternateCharacterInterpretation: Mikhail Arbatov. Is he someone deeply infatuated with Fei Long or just a brat out to cause trouble? [[spoiler: WordOfGod strongly implies it's the former.]]
* EnsembleDarkhorse:
** Fei Long's massive popularity outside of Japan reportedly surprised his creator, and it's enough to save him from his original planned fate of dying on a shooting rampage.
** Mikhail is very popular in the fanbase as well.
* EvilIsCool: A lot of the main and supporting cast who ''aren't'' the bad guys are involved with criminal organizations, but Yamane Ayano is able to give them so much appeal, style, and personality that the readers can't help but root for them.
* FoeYayShipping: Fei Long and Asami, particularly on Fei Long's side. Also Fei Long and Akihito.
* {{Moe}}: Hiroto, the infant that Akihito had to babysit for a few days in the "Little Monster +1" extra.
* ShipToShipCombat: Simply put, a good chunk of the fandom is divided in whether they ship Fei Long with either Yoh or Mikhail.
* TheWoobie: Fei Long because of his brother and early life. Akihito once he meets Asami.
