The King of Fighters XIIIEdit
- Andy: "You're as keen as a blade, and your resolve is strong.... Very impressive!"
- Leona: "You're pretty fearsome yourself...."
- Andy: "But what I seek lies beyond the face of death! Andy Bogard, master of the Shiranui style! Ready to fight!"
- Ash: "You're keeping me under surveillance, but you're doing a very poor job of hiding it.... I'm getting sick of having you follow me around. I have stuff to do, so retire already!"
- Leona: "I am only carrying out my mission. Your problems do not concern me."
- Athena: "U-Ummm.... Leona? Are you feeling okay?"
- Leona: "I'm fine.... Why do you ask...?"
- Athena: "...I can't just say that she looks even moodier than usual, can I?"
- Leona: "Do you have a problem with me looking moody?"
- Athena: "Eek! Did I just say that out loud!?"
- Leona: "Don't worry about thinking that I look moody. I certainly don't mind."
- Athena: "S-Somehow, your indifference only makes me feel worse...."
- Benimaru: "Rowrr. Hello there, miss! How about after we're done getting to know each other in the ring we get to know each other over dinner?"
- Leona: "...Okay. I have nothing to do after my mission."
- Benimaru: "Hm.... I guess you must like what you see as much as I do."
- Leona: "Yup. And what I see is that you have no chance of winning."
- Leona: "Please leave quietly.... This is no place for amateurs."
- Billy: "You're callin' me an amateur? Me!? An amateur!? You'll live to regret those words, girly!"
- Leona: "You have no self-control.... That is proof you are no professional...."
- Chin: "You must have seen a lot in your young life already.... But take comfort in knowing that you are following the right path. Never waver, listen to your heart, and always stay devoted to your cause!"
- Leona: "I will not stop.... Thank you."
- Chin: "Ho ho ho! Let me do what I can to help you increase your mental fortitude!"
- Clark: "All right, the loser gets the winner's back, just like always. Got that, Leona?"
- Leona: "Understood. The loser will become the victor's backup."
- Clark: "But no holding back, and no rigging the fight, okay? You know th Colonel's views on that."
- Leona: "Understood. Resuming mission...."
- Duo Lon: "Do you know Ron's whereabouts?"
- Leona: "Even if I did.... What makes you think I'd tell you?"
- Duo Lon: "Never mind then. Just forget I asked."
- Elisabeth: "You carry the cursed blood of one born from the union of a human and a member of the Orochi Clan.... If you want to press on, then show me where your heart lies!"
- Leona: "I can overcome this on my own.... I will not stop moving forward...."
- Ash: "Behold, child of Orochi! Watch as I turn your leader into a miserable little pile of ashes!"
- Leona: "I am not Orochi... I'll stop you as a human being!"
- Ash: "That's what makes you people so foolish. You think humans can actually stop me!?"
- Saiki: "What do you want? Why is a girl with the blood of Orochi walking around amongst humans?"
- Leona: "I am a human. I am not Orochi."
- Saiki: "You will never be human. Unfortunately, you will likely never be Orochi either. You would be better off dead! Let me bestow this act of mercy upon you!"
- Daimon: "......"
- Leona: "......"
- Daimon: "............"
- Leona: "............"
- Daimon: "So.... I'm gonna attack you now...."
- Leona: "Sure.... I'm ready...."
- Leona: "I'm going to restrain you... You are allowed to resist, but I don't think it will help."
- Saiki: "Hehehe... You miserable Orochi failure! You have some real guts to talk big in front of me! I know! Let me give you an appropriate reward! How does an honorable death on the battlefield sound?"
- Hwa Jai: "Hmph. You've got a good pair of eyes for a kid. They look as if they've seen a lot."
- Leona: "Yes.... Probably a lot more than yours."
- Hwa Jai: "Hey, don't get all full of yourself just because I praised you a bit! Show me what you've seen that makes you so special!"
- Leona: "I'm not like you... I'll keep resisting what's in my blood."
- Iori: "Wipe that smug look off of your face... Your banter never fails to bore me... I've taken all the boredom I can stand! Die already!"
Iori with the Power of Flames
- Leona: "Please leave without causing trouble... You're a liability to our mission."
- Iori: "I don't care about you people or your stupid missions... Or are you going to do something about it?"
- Leona: "No problem... Executing the mission..."
- Joe: "I won't be so boorish as to make fun of you for being a woman. Come and get it if you've got what it takes!"
- Leona: "I will. That is my mission."
- Joe: "Great, let's do this! I'll show you the strength of an unbeaten champion!"
- Kim: "You there! What would you think of studying Tae Kwon Do for your spiritual improvement?"
- Leona: "I don't need any more skill... I need to learn to overcome my fears."
- Leona: "Target located. Starting mission."
- King: "You're a straightforward one! Well, why waste words, right? Okay, "Mission Start" for me too!"
- Kyo: "Hey, you are not going to go all crazy on me again, are you?"
- Leona: "I think I have it all under control now... I will not back down..."
- Kyo: "What!? So you could explode any minute? Again!? Get out of here! This is no place for people who can't control themselves!"
- Leona: "Could you get out of my way, please? I don't feel like wasting time and effort on you."
- Mai: "What's the matter? Scared? Just admit that you are!"
- Leona: "I simply do not see why you'd want to be beaten so much."
- Mai: "You shouldn't say things like that if you're trying to avoid a fight, missy."
- Mature: "Don't you ever feel like just letting go and using your power for your own good more? Listen to the longing deep in your soul!"
- Leona: "I will not make the same mistakes again...."
- Kyo: "It always hurts me to look at you. You claim to have overcome the curse of your blood. Be honest with me. You're still not completely over the past, are you? I can tell just by fighting you."
- Leona: "...Even so, I cannot run away anymore. I've decided I have to live with this fate."
- Kyo "I'll say this: You know what you're doing, I can only honor that by fighting you without holding back. Let's go!"
The King of Fighters XIVEdit
- Mature: ""Don't hesitate"... You hesitated the moment you said that, don't you think?"
- Leona: "I don't. I wasn't saying it to myself."

- Leona: "Maybe you can't tell, but it's obvious to my friends."
- Mature: "Hmph... What does that mean?"
- Ralf: "Hey, you having fun?"
- Leona: "No, Colonel. I'm in the middle of an operation."

- Ralf: "Hehe, well then, shall I give you some coaching?!"
- "For me to be careless during a match... Impossible."
- "I do not intend to forget the past. But I also do not intend to throw away the future."
- "If you interfere with my mission any more, I won't show any mercy."

- "My friends are waiting. I'm going to take off first."
- "Sorry for taking your fun away, but this isn't a game for me, either."
- "Go home you shouldn't be standing on this stage."
- "This is not a battlefield. Losing does not mean death."
- "You lost, I won. That is all."
- "Sorry for being hard on you. Losses are not acceptable for my mission."
- "I controlled my strength, but... Even so you're really torn up."
- "Giving up is much scarier than losing."
