Sonya is one of the main characters of Monster Girl Quest: Paradox. She is Karen`s daughter and Luka`s childhood friend. She is quite childish, getting excited over adventures but easily frightened although she is capable of being serious when the situation calls for it.
Sonya will join as soon as you talk to the chief and leave his house. However, you can leave Iliasville without talking to the chief to not recruit her. In doing so you will not obtain the Pocket Castle, which also means you will not be able to recruit any random monsters at all. Sonya will then join near the end of part two, right before the Snow Cave, having been brought there by the White Rabbit.
Sonya is first met on the way to Luka's baptism. She was tired of waiting for Luka who was running late and went to find him. They proceed to Luka's baptism where she assists the head priest. Ilias appears surprising everyone present. Sonya runs off but quickly returns to tell Luka two little girls are fighting in his inn. After Luka ends the squabble and says his good byes to village elder, he meet Sonya waiting outside the chief's house. She forces her way into the party, not wanting to be left out of an adventure or risk letting Luka get hurt by going off on his own.
Before they can leave the village, Nero shows and starts talking to Luka. During the conversation, Sonya notices Nero has been staring at her and she asks why. He apologizes and asks for her name but when she introduces herself as Luka's childhood friend, he blurts out Luka doesn't have one. She gets upset causing Nero to apologize and leave.
After that weird conversation, Sonya tells Luka about how there is a Slime Girl in trouble. Luka asks whether or not that is her job to deal with which she shrugs off.
Sonya: “I can't stand house-sitting. Hey Luka, hurry up and take me with you!”
Nuruko: “Kyuu! Kyuu!”
Sonya: “You want to eat an apple? Just wait a minute; I'll cut it up.”
Luka: “Sonya, you can understand Nuruko?”
Sonya: “You can't understand her, Luka? From the sound of her voice, it's obvious she wants an apple.”
Sonya: “No fish. You've been eating too many lately. You need balanced nutrition, got it?”
Luka: “(...I don't understand.)“
Hip: “You're... a fellow club user! Are you an orc too?”
Sonya: “No, I'm human. Can't you tell just by looking?”
Sonya: “Hey! Why aren't you saying anything?!”
Hip: “No, your voluptuousness is clearly that of an orc.”
Sonya: “Hild, your hair's grown out. Want me to cut it?”
Hild: “Hild's hair? I leave it to Sonya.”
Sonya: “All right. *Snip* *Snip* ...There.”
Hild: “Hild will cut Sonya's hair as well. Activating Death Beam...”
Sonya: “...I decline.”
Radio: “MistreSS Sonya...”
Sonya: “We're friends, Radio. You can just call me Sonya.”
Radio: “Then please CAll me a piece of junk. That's what my beST friend used to call me...”
Sonya: “Were they really your friend...?”
With Spider Princess:
Spider Princess: “Oh, you're quite the nuisance. Are you still buzzing around my betrothed...?”
Sonya: “Apart from that, I've been curious... Isn't “betrothed“ the word you use for a woman's husband?”
Spider Princess: “I'm old-fashioned, so that's what I call him. It's not a very narrow-minded thing to say.”
Sonya: “Eh? You're an old lady...?”
Spider Princess: “Y-you...!”
Lazarus: “Oi, Luka... Sonya won't talk to me anymore.”
Luka: “Because you've been hiding that you were the Don of the mafia all this time... Frankly, you're reaping what you've sown.”
Lazarus: “It's none of your business...”
Lazarus: “What the hell's with you girls?! You really shouldn't get involved!”
Sonya: “When you joined up with Uncle Lazarus, you weren't doing anything bad were you...?”
Merlin: “To rule over evil is not necessarily evil in itself. Rather, you should think of it as restraining and controlling evil?”
Sonya: “That's sophistry, isn't it?”
Merlin: “Yes, you are right.”
Sonya: “Don't admit it so readily... An old man can't support himself.”
Merlin: “I represent the Don. I won't be troubled so easily with surviving.”
Sara: “Oh, Sonya. Have you had the rice in the dining room?”
Sonya: “Yup! I had it in their new dish, the salmon bowl.”
Luka: “Sonya, Sara, you two seem to get along.”
Sonya: “There weren't any girls my age in the village. She's like the friend I never had.”
Sara: “The same goes for me. I guess you could say we're girlfriends.”
Sonya: “Yeah. ...Huh?!”
With Grand Noah Queen:
Sonya: “Umm, is this really okay? You're out on an adventure even though you're a queen...”
Queen of Grand Noah: “Meda-- ...Ensuring the safety of the world is part of a ruler's duties. To that end, it is appropriate for me to be willing to go on a long journey.”
Sonya: “(...She almost said 'medals.')“
She is required in the “Sonya’s 1000 knocks“ scene.
Sonya: “I wonder how uncle Lazarus is doing? I should write him a letter.”
Sonya begins to write a letter.
Sonya: “Sei! Deyaa!!”
