Eva Cruz

She/he/they, 21(year 845), 196cm

She comes from a family of well-known shoemakers in Utopia district. Her mother was a scout, but died tragicly when Eva was 7, which led her to join Survey Corps, herself to take revenge on the titans. His father wanted him to be his apprentice due to her being his only heir(he couldn't bring himself to remarry and has never truly moved on. Eva sees and his grief which is also the reason why she joined SC, hoping when the titans will finally disappear, her father will finally live at peace)
She's very serious with herself(sometimes even too serious), has a tendency to overwork himself 'till he's close to collapse from exhaustion, so her team has to remind her to rest and eat. Her sharp thinking and strategic skills made her a pretty recognisable figure in the SC, even 12th and 13th SC commanders were welcome to here her new ideas.
His relationship with gender is quite simple; "We are at war, does it really matter to be recognised as a woman or a man? At the end I am just another person who faces death alongside you." They don't have preffered pronouns, so call them literaly whatever, just respect her and see her as a person. Actually, Kira was his first profound partner. Before her, she had some expirience, but those were just situationships with one-night stands, nothing long-term. Eva and Kira met during one expedition in the med tent when both were badly injured, which later brought them close to each other.
Eva also has a bad habit of overspending. He has his wit, but always will buy the most unnessesery items because they were on a "great discount". Especially loves to spend money on his girlfriend (even tho Kira is much wealthier than them, so there's literaly no need for them to buy her things), who later buys her partner meals when they eventually go broke after another shopping haul. It hurts Eva's ego, but they have no other choice, because otherwise they would just starve himself.

(their hair color is something in between red and purple)

Kira Tepesh

She/her, 22(year 845), 172cm

Her family residents in the capital and has many members in the highest branches of Military Police, even in royal government. So, since she was a child, she had been trained to become a soldier in the MPs. However, afterwards the cadet training Kira didn't get promoted to the Top 10, therefore she joined SCs, in order to run away from the dishonor she brought and to have a slight chance to prove her strength through slaying titans. To this day the rest of her family is treating her position with disrespect and pushes her away, as if she was a debris, needed to be swipped under the rug. Because of that, she pushes herself to her limits over and over, just to get a glimpse of acceptance from her family, but at the same time Kira discovered her talent at manual work/tech.
She has never been good physicaly nor at flying with 3dmg. She be has joined science team and creates innovaitve projects, not seeing how this makes her feel fulfilled due to the need for gratification from her family (Like; "i may just created a brilliant way of improving 3dmg into much faster and sturdy version, but it doesnt matter because i only killed 5 titans by myself in my whole life"). Due to living with constand disappointment with herself she developed a very feisty, perfectiotist personality. Even smallest mistakes or if something doesn't go along her plan, she just gets impulsive and furious. Normaly, she's quite joyous and optimistic, ready to help anyone.
On one mission, she accidently hit a tree at a high speed and had to be quickly transported to the med tent. She was terrified of dying without proving her worth, she asked the scout to hold her hand so she could FEEL something. Unfortunatly that scout had to run back to the battlefield to help others, so she asked the someone who laid next to her. That someone was obviously, Eva. They held hands untill the next morning just to make sure theyre both alive, and later got closer with each other.
Kira is also a total social butterfly. While Eva's attidute might seem unwelcome at first, Kira with her easiness at makeing friends, helps him connect with others. She even managed to greatly surprise her partner by being friends with commander Erwin Smith since he still was a Capitan, and she wasn't even a cadet(they met on one of the banquets in the capitol).
