The hero of justice, Catherine, is here, along with Yodogawa!

Catherine Kyoubashi is a playable character in the Arcana Heart series. She is a third generation Japanese-American who is a young genius, just like her friend and rival, Kira Daidouji. She pilots her mechanical robot, Terry Yodogawa, to battle.

Her Arcana is Medein, the Arcana of Magnetism.


Catherine is a young tan-skinned girl with blue-ish purple eyes and blonde hair. She wears a red visor with a pair of white bunny ears, a red one-piece backless swimsuit with a white star on the chest area and white wristbands.


Please put detailed description.


A third generation Japanese-American, Catherine's grandmother was from Osaka, which explains why someone with platinum-blond hair and blue eyes speaks exclusively in the Kansai dialect when speaking Japanese, and why someone as young as her sounds like she's eighty years old. A curious combination of Kansai impatience and American laxity, her boisterous and carefree personality makes her an enigma to both sides of her family. Catherine tends to wear her heart on her sleeve, and her emotions are there for all to see.

Like her friend and rival, Kira Daidouji, she is a genius who obtained her doctorate in celestial mechanical engineering from the Celestial University of Massachusetts at the age of ten. Terry Yodogawa, the robot she created and built herself, rivals that of anything thought up by Kira. Catherine also shows a somewhat masochistic streak, as she loves nothing more than to be challenged and insulted by Kira.

Petra offered Catherine support for the research and development for Terry Yodogawa, prompting Catherine to join the Rosenberg branch of the European Celestial Union. Feeling a sense of obligation, she now takes on missions to eradicate the Drexler Institute and eliminate the planar rifts appearing around Japan.

  • I'm starving! Boy, I could really use some okonomiyaki right now... Then maybe I could work a little harder! ♪
  • Now, shall we continue? So long as takoyaki and okonomiyaki wait for me at the end of the road. I'll keep on fighting!
  • Oh boy... This won't do... I need to eat some takoyaki and get my head on straight!
  • What?! Yodogawa's broken!? I've gotta fix him up quick! I'll fix him up good too, so he'll be able to keep up with Formula 1 race cars!
  • Yodogawa! Calm down. You got it all wrong! We didn't screw up! It's just...bad...luck?
  • I give up, I give up! Yodogawa and I have our ups and downs, too... Next time, I'll do better. ♪
  • NEXT! Bring on the next one! We'll show you just how powerful we are! Huh? Wait, we're losing? No way!
  • It was just a series of unlikely coincidences that caused me to lose! ♪ Wah ha ha ha! A real man would turn the tide of battle right here! ♪

After Battle

  • Please don't tell me you're trying to give me a nickname. Well, if you have to, how about "Captain Cathy"!? Oh wait... That's super lame, isn't it... (Heart Aino)
  • Someday, Yodogawa will be the foundation for everything in our world! This is only the first step! You're going to be a living part of history! (Saki Tsuzura)
  • Good or evil, being a scientist is about self-discovery and pitting yourself against your peers. (Kamui Tokinomiya)
  • Whoa, that's not good! A dog as big Yodogawa wouldn't be cute at all! Wouldn't that make your master sad?! (Konoha)
  • Thanks! I'm sure someone will pick it up. Petra's funding the development right now! I'm going to get some results! (Maori Kasuga)
  • Hey, that's not fair! Yodogawa's designed to be for general purpose use! There's no other robot out there that can beat this all-purpose-ness! (Lilica Felchenerow)
  • Yodogawa's engine is a hybrid that uses celestial energy to combine hydrogen from the air with ether and oxygen to create an EXPLOSION! It's intense! (Lieselotte Achenbach)
  • That's a great idea! I'd love to see my Yodogawa fight your golem! (Yoriko Yasuzumi)
  • Well, it uses ether to power its engine, so... I guess maybe it would convert it into exhaust...? (Fiona Mayfield)
  • Just leave Yodogawa's development, the planar rifts, and the search for the celestial stones to me! Your sponsorship makes all of this possible! (Petra Johanna Lagerkvist)
  • That's right, Yodogawa's big enough to protect everyone. *Sniff* Isn't it touching? (Zenia Valov)
  • Well, thanks for thinking of me! Besides, I'm happy to get training from somebody as powerful as you! (Elsa la Conti)
  • Oh...uh, yeah... My mission's fine. I can do research while I work. I think maybe "tee-hee" was going a bit far, though. (Clarice de Lanza)
  • Awwwwwww! You can always come to your big sister Cathy when you're feeling down! I'm always on your side! (Dorothy Albright)
  • Thank you! Thank you so much, Dorothykins! With your kindness... I can eat three takoyaki! (Dorothy Albright with Celestial Stone)
  • Whoa! There's a dent in Yodogawa's stomach! How do you dent ethereal carbon steel!? Is your foot made out of some special alloy?! (Akane Inuwaka)
  • Well, if it makes you happy, then it makes me happy! I'm gonna do my best! Let's go, Yodogawa! Blast off at the speed of light! (Nazuna Inuwaka)
  • A lot of celestial stones?! Are you serious!? Well, as tempting as that is, I can't mass-produce Yodogawa yet. Sorry... (Angelia Avallone)
  • I'm sorry, but I'm on a mission to secure more celestial stones right now. Besides, I need it for research, so I wouldn't give it to you anyway. (With Celestial Stone)
  • Thank you! I'm the sort of girl who does her best work when she gets compliments! Don't worry, I'll keep on it! (Rosenberg member with Celestial Stone)


  • I'm all fired up! You hurt Mei-Fang, and now I'm gonna beat the crap outta you! You're gonna beg for forgiveness! Catherine Kyoubashi is a woman who values tradition! Mei-Fang, you will be avenged! Watch over me from heaven, my friend! (Mei-Fang Defeated)
  • Ahh. Thank you so much! ♪ You beat Kira up just for me, didn't you? Oh, I think I might be falling for yooooouuuu! As if! You really think I'd say that?! Kira is my rival, but she was also my friend! I'm gonna pound that through your thick skull! (Kira Defeated)
  • Awww... Poor Dorothykins... She'd only just moved to Japan, and she was trying so hard... Who would do such a horrible thing... It's no use playing dumb! I know it was you! Dorothykins is a star now, but I can still hear her voice! It says to take revenge! Here I come! (Dorothy Defeated)

After Revenge

  • I have days where I want to get revenge too. But don't you think that knowing when to hold back is the sign of a true woman?
  • I'm gonna win, for the sake of the legend of Yodogawa! It's our fate to just keep on winning! I'm sorry... Really, for real.

  • Advanced technology! Yodogawa's advanced technology! I doubt a little kid like you could understand. I will never give up on advanced technology, even if I die. (vs. Lieselotte Achenbach)
  • How do I say this? Usually, if I beat something like a "demon lord," people would be going nuts and telling me how great I am, so... What's this weird feeling? (vs. Yoriko Yasuzumi)
  • I know why your blob can't defeat me! It's the drill! You don't have enough drill! (vs. Kira Daidouji)
  • A person ascending to a higher level of being... So the moment you turn ethereal, you gain all sorts of knowledge! Maybe I should become a spirit too... (vs. Fiona Mayfield)
  • How's that? This Yodogawa! It's all thanks to Petra that he's this big! (vs. Petra Johanna Lagerkvist)

  • Oh, little Weiss... Being big isn't necessarily bad! The bigger Yodogawa gets, the bigger the dreams he ignites are! (vs. Weiss)
