Their Sun (JJBA: Stardust Crusaders)

Chapter Text


"When someone threatens me, I don't feel scared and say 'Why Me?'. I smile and say, 'Try me.'"

Sophia Perez is an ally to Jotaro Kujo and the members of the Stardust Crusaders. Sophia is a half American and half Italian teenager who lived all her life in America, but started going on more trips around the world when she met Joseph Joestar and became his assistant. She lived an ordinary life before she got caught up with the Joestars despite some family drama that she has left in the past. When Jotaro's mother, Holly, got sick due to DIO, she goes with Jotaro and the others to kill Dio. She holds one of the most powerful stands with an insane power, Solar.

-Reading and Writing




Sophia is short with larger hips and chest than most people her age. She bares resemblance to her mother in some areas while also adopting some of her father's appearance(hair and eye color). She has fair, milky skin which gets a bit tanner the longer the series goes on. She never wears makeup. Ever. When Jean asked why did she not wear makeup, she asked, in reply, why do girls wear makeup. This kept him quiet for a couple of hours. Her attire changes throughout the adventure, the other members having no idea where she gets these clothes, to which she replies it's a secret, but she usually wears the same headphones that her mother got her. They are either on her head when listening to music or around her neck when she's fighting or when she is talking to the others.


Personality and Relationships


Sophia is generally quiet and doesn't really try to cause trouble in the gang or throw herself into trouble(which Jotaro was more than happy about). She sometimes will strike up a casual conversation between the group about what they do at home and ask them some simple questions, such as their hobbies, goals, or interests. It soon appeared to them that she did this in order for everyone to relax a little bit, as this mission was high risk. She is sort of an optimist, but was definitely a realist. She didn't pull none of that 'we can do this if we work together!' stuff, she was real about situations and always considered options. She is friendly and someone can make her laugh easily if they really wanted to. Puns sometimes get her good. She is also sort of motherly, as she shows deep concern when one of the members or injured or ended up in a dangerous situation. When it's her and someone she trusts, she might be a bit more talkative and chatty, but if that person isn't in the mood to talk, she respects it and stops.


Jotaro Kujo

Nobody expected this at all, but these two might be the closest in the whole group. Jotaro respects her because she is quiet and a realist, sometimes listening to music with her. He also respects her capabilities and power and states occasionally that they were lucky to have her on their side as she would be a deadly opponent. He also shows some concern when she gets injured and it's clear to everyone that he respects her. She feels the same, respecting his wit and his abilities and has even stated that she could trust Jotaro with her life and has said many good things about Jotaro despite his occasional attitude. They disagree with each other sometimes, but respectfully, never losing their cool with each other.

Joseph Joestar

What does she even say about him? They may get a little goofy with each other sometimes and his puns sometimes make her laugh. Occasionally she will listen to music with him, but this is very rare. The only times she listens to music with him is when they are traveling on a vehicle. He respects the girl greatly due to her strength, determination, and dedication to her family; as she reminds him a lot of Caesar in that way. She respects him because he not only gave her a job, but they have saved each other on multiple occasions.

Holly Kujo

Holly is a sweet woman and easily earned Sophia's deep respects. She helps with cooking and even made Holly breakfast when she wasn't able to cook the day she got sick, taking care of her with Joseph. Holly enjoys having Sophia around as the girl has a lot of positive energy. And what more could she ask for when Sophia gets along swimmingly with her son?

Muhammad Avdol

She met him with Joseph in Egypt and got along well with him. In fact, he is the one who helped her get enough control over her stand that she can use it somewhat decently. He continues to help her develop and has earned Sophia's trust. She finds him just a bit amusing and they always make fire jokes together after they reunite since the Hol Horse incident. She displays a sort of protectiveness around him and slams someone down when they try to insult him. She respects him deeply and they often have casual chats but nothing serious.

Noriaki Kakyoin

They get along pretty well too. He shows her respect for her abilities and understands her confusion and her inability to be able to relate with other people who didn't have stands and couldn't see them. They became pretty quick friends and they often do chores together or do some minor shopping when getting things the group needs. She finds his tongue thing a little creepy though...

Jean Pierre Polnareff

He's probably the biggest goof there is. She laughs at some of the things he does and sometimes casually makes fun of him, but it's all good between them. She sometimes spares him some kindness and sometimes tells him the things he needs to hear in order to cheer up. When Devo locked her in the bathroom and had it fill to the brim with blood, he was the one who saved her. Afterwards, she sympathized with him and his situation with bathrooms, as she was victim to blood filling up in the bathroom at a rapid speed.


What does she say about this fuckin' dog? She isn't the biggest fan of dogs, but she doesn't hate them. But Iggy...likes to test her patience. She related him to the dog she has at home with her mother and father and how he's such a spoiled dog and a brat. Iggy takes offense to this, but...she can kind of easily overpower him with her dark solar manipulation. After his death, she mourns him out of respect for having been loyal to the group despite his hatred of it and his ability. 


This fucking bitch.


Power and Abilities


Sophia has the stand Solar, which is a stand made of mostly fire and dark energy taking a humanoid form. It's one of the most powerful stands in the series and can obliterate most of the squad if she loses control over it. Fortunately, this never happens as Sophia manages to stay calm in almost every situation. She almost once lost it at Dan of Steel, a dark flames having been about to appear in her hand before Jotaro manages to calm her and made sure he took the brunt of things, but that seemed to make her feel only worse. Her stand has Dark and Pure Solar Manipulation. Dark Solar Manipulation is the power to manipulate the dark/destructive aspects of the sun/solar energy. Combination of Solar Manipulation and Negative Forces Manipulation. Opposite to Pure Solar Manipulation. User can create, shape and manipulate the solar energy/matter of a darker, detrimental nature; that which damages, destroys, and consumes anything/everything they come across, representing the hazardous destructive side of sun, which in turn ignores most of the limitations and weaknesses of normal solar energy/matter. In essence, this is about solely controlling the negative powers of the sun. Pure Solar Manipulation is the ability to manipulate the beneficial aspects of the sun. Combination of Positive Forces Manipulation and Solar Manipulation. Opposite of Dark Solar Manipulation. User can create, shape and manipulate solar energy of beneficial nature; that which strengthens, enhances and causes anything/everything it comes across to flourish, representing the sustaining and preserving side of earth, which in turn ignores most of the common limitations and weaknesses of its normal elemental variety. In essence, this is about solely controlling the positive powers of the sun.


Wisdom - "Knowledge is knowing a tomato is a fruit, wisdom is not putting it in a fruit salad."

Calm - Sophia shows more emotions than Jotaro, of course, but she never seems to really get angry unless something hit close to home. Any insults thrown at her don't do much, depending on the insults.

Power - She has a lot of destructive power and sometimes can have her powers get extremely destructive and can rip apart an entire building if she lost control.

Creativity - She is creative and her tactics are strange, but genius. One time, she let her opponent get very close to ending her life, then, last minute, she took advantage of his every weakness and killed him.
