- Adorkable: Outside battle, Weiß's a complete, adorable klutz who knows nothing about social life.
- Badass Decay: Lieselotte Achenbach. In the original Arcana Heart, she's a bonafide Enfant Terrible assassin. Afterwards, she began to mellow out as a Jerkass Woobie.
- Broken Base: There are some Fighting Game veterans that have a cold reception to the series just because it has an all-girls cast filled with Boobs of Steel, Gag Boobs, Fanservice, and Stripperific characters. Being an animesque series as well hasn't help matters in this regard. Others, however, consider this criticism to be hypocritical due to other fighting games having similar characters.
- Cliché Storm: The entire series could be considered this, with a ninja girl with dog ears, a water-powered catgirl, a roller skating demon girl, a female Chinese android with Boobs of Steel, mikos with Boobs of Steel, you name it.
- Konoha's short physique helps her avoid many attacks, but she has a pretty short range.
- Elsa. Depending on Arcana selection, she has several infinite combos in Arcana Heart 3.
- Genius Bonus: Akane Inuwaka's Arcana is named after the fennec, a type of fox with prominently large ears. Knowing that, check out her ears under that do-rag.
- Hilarious in Hindsight: The April Fools' crossover involving BlazBlue is all the more amusing because Heart Aino was announced for BlazBlue: Cross Tag Battle.
- Ho Yay: Most of the girls have something for another:
- The constant subtext (and later almost flat-out text) between Heart and Saki.
- Mei-Fang seems to have shades of this with her creator. In her Arcana Heart 3 ending, it seems to be more than just shades.
- Mildred and Fiona. One of the mid game scenes in the original game has Mildred holding Fiona in a rather, intimate looking way with her hand on Fiona's cheek and her face right next to Mildred's breasts. In Fiona's bad ending, Mildred is truly hurt by Fiona's betrayal.
- Particularly notable with Clarice di Lanza, in that there is no such thing as subtext regarding her fixation with Elsa la Conti.
- Konoha primary goal life seems to be gain attention from Kamui. At times their relationship resembles a pet and owner, given Konoha's desire to being petted like a dog and have her belly rubbed. However, since Konoha is only interested in those things if it's from Kamui, coupled with her ending 3, it appears closer to romantic feelings on her part.
- Scharlachrot and Weiß. The latter's main goal is trying to find the former, the latter goes berserk in arcade mode at the thought of the former not being able to find her. In arcade story modes where Weiß does come for her, Scharlachrot goes berserk because she wasn't exclusively thinking about her. Even when she's free from her brainwashing, Scharlachrot is still a Clingy Jealous Girl around Weiß as she's the only connection she has to the world.
- Memetic Badass: Parace L'Sia is widely hailed as one of the most brutal and difficult fighting game bosses ever.
- Moe: The first fully Moe fighting game franchise.
- Porting Disaster: The PlayStation 2 version of Suggoi! Arcana Heart 2 suffers from slowdown, frame rate drop, and downgraded graphics and sprites.
- Surprisingly Improved Sequel: The first game was a pretty good game, while the console version of the second game was a Porting Disaster. The third game, however, blows both of its predecessors out of the water big time.
- That One Boss:
- Mildred in the first game. During the first phase of the battle, she's in a cocoon like object while she transforms into her archangel form. She's protected by two orbiting Attack Drones that fire projectiles that cover the length of the stage and only reliable way to attack her without getting defeated is if the player has a character or Arcana with good projectiles. She's fought in her archangel form regardless of whether the player wins or loses. However, if the player doesn't defeat her during the first phase, she starts the match off with a maximum super meter. Furthermore, she has a collection of all the best moves in the game, and she can dish out more damage with a special move than the player can with a super move. Finally, Mildred has a screen filling super that will take half of the player's health if she catches them off guard.
- In Suggoi! Arcana Heart 2, Parace L'Sia, like Mildred, has a collection of the game's best moves. However, she has less health. That doesn't matter because she recovers her health gradually, and her regular attacks have range akin to projectiles that comes out too fast to dodge. Parace also has a One-Hit KO super move that cannot be dodged, another super move that allows her to rapidly heal herself and refill her super meter, and she teleports like crazy. In 3's Score Attack, she's somehow even worse, which quite possibly makes her the single hardest fighting game boss ever. While her above mentioned super move is no longer a one hit KO, she is able to reads your inputs and is far more aggressive. She can easily pull off combos that will deplete your lifebar if she manages to hit you even once. She teleports a lot more as well, making even hitting her a chore. Pretty much the only reliable way to beat Parace is to try again and again, because the more times you lose to her the less health she starts the fight with. As of LOVE MAX!!!!!, however, the final part doesn't happen anymore as she's a fought as a challenge separate from Score Attack. Good Luck.
- Viewer Gender Confusion: Raise your hand if you think that had it not been her name and the fact that this is an all-girls fighting game series, you might pass up Dorothy Albright as a cute little boy.
- Widget Series: All. Moe. Fighting. Game. The fact that it actually stands on its own merits is notable.
- The Woobie: Every time Fiona loses, she ends up crying and pleading for the opponent to stay away from Mildred.
YMMV / Arcana Heart
