- Acting for Two:
- In the Japanese version, Hangetsu, Mikazuki and Mangetsu Tsukuyomi are all voiced by Chinatsu Akasaki. Averted in the English dub, where the Tsukuyomi sisters are played by separate voice actors.
- In the English dub:
- Ryoma Kurogane and Sirius Vermillion are both voiced by Josh Morrison.
- Young Ikki and Renren Tomaru are played by Tiffany Grant.
- All-Star Cast: The anime features Ryota Ohsaka, Shizuka Ishigami, Nao Tōyama, Shintaro Asanuma, Yuu Kobayashi, Hisako Kanemoto, Yoshitsugu Matsuoka, Yoshimasa Hosoya, Mugihito, Show Hayami and Hideyuki Hori.
- Cross-Dressing Voices: Megumi Han and Kalin Coates as Utakata Misogi.
- Dueling Shows: With The Asterisk War, which has a similar premise of being basically an Unwanted Harem show set in an Academy of Adventure where students duel each other with Magitek. Bonus points for airing on literally the same day and close to the same time slot too. Not only that, for the first two thirds of the season, both series more or less hit the exact same plot points at the same points in the same episodes. Chivalry is more comedic and lacks most of Asterisk War's social science fiction aspects. Its anime was also not as successful, running for only one twelve-episode season (Asterisk War got two).
- Fan Nickname:
- Hypothetical Casting: Christina Kelly stated on ask.fm that she would voice Stella if the anime would be dubbed into English. However, Luci Christian would end up voicing Stella.
- I Knew It!: When Sentai Filmworks released their February 2017 newsletter, many guessed that the series would be given a home video release with an English dub since Sentai usually announces the releases four months in advance. They were right.
- Milestone Celebration: The anime adaptation marked the 10th anniversary of SB Creative's GA Bunko label along with Is It Wrong to Try to Pick Up Girls in a Dungeon?, Nyaruko: Crawling With Love!, Undefeated Bahamut Chronicle and Hundred.
- Name's the Same:
- The Tournament Arc is named The Seven Stars Sword Art Festival. Seven Stars is also the name of the ruling family clans of Gjallarhorn - coincidentally, the entirety of the anime adaptation ran alongside the first half of Gundam IBO.
- There is a group named Akatsuki, where Ikki's brother is a member. A coincidence? probably not.
- Playing Against Type: Yoshitsugu Matsuoka usually plays Nice Guy protagonists for Light Novel adaptations, which makes the fact that he's voicing Kirihara of all people very jarring. Though one thing Kirihara has in common with many of Matsuoka's other characters is his Chick Magnet status◊. However, this isn't the first time he's done this.
- Queer Character, Queer Actor: In the English dub, the non-operative trans woman Nagi Arisuin is played by gay voice actor Chris Patton.
- Sleeper Hit: By the time the anime premiered, nobody expected the series to be a hit given that it aired alongside The Asterisk War. Hoo, boy, were they wrong by the time episode 4 premiered; the twist that Stella and Ikki would start a romantic relationship removed all pretenses that this show would be another generic battle harem. From that point onward it only started becoming more and more apparent that it wasn't going to be another generic light novel adaptation and considering the parallels to The Asterisk War, many noticed it was doing what that show did... but better! This show also aired the same season as One-Punch Man and the highly anticipated second seasons of Noragami and Haikyuu!!, making its unexpected success even more surprising.
- What Could Have Been: Christina Kelly stated that she would possibly voice Stella when the series would be dubbed into English before Luci Christian was cast.
- The Wiki Rule: Has a wiki here.
