I match you with Giyu Tomioka!
At first glance, Giyu doesn't probably pay much attention to you, but he wasn't the type to abandon a hurt sparrow if he ever found one.
You're a clear newbie when it comes to slaying Demons and you need to be trained properly to fight against them so you won't die. There is no place for weakness in corps.
Giyu isn't really the type that accepts Tsugukos but he makes an exception for you because of how shy and awkward you are...
But when the two of you train and you get more and more comfortable with him, you start opening up, and suddenly that little sparrow turns out to be an actual songbird.
You're bubbly, playful, and happy and that is the complete opposite of Giyu... But you know what they say, opposites attract each other.
But you aren't complete opposites. Much like Giyu, you don't really like loud noises, or crowds and you both would rather stay home than go out.
Giyu feels like he doesn't deserve you, not after everything that has happened, but you aren't only kind but forgiving and supportive. You don't want to see him beating himself up for something that was already in the past and you want to help him to be happy as best as you can. Here is when your sensitivity comes into use.
No one knows when or how, but the two of you kind of became a couple? How did that happen?
You're definitely the more outspoken one in this relationship and Giyu doesn't mind it one bit. He is rather quiet so having you do the talking works for him very well.
The Hashira thinks you are talented when it comes to your instruments and he will happily listen you play some. He doesn't really show it, but he is happy, trust me.
He takes notes on your likes and dislikes and acts according to them. If he sees something you might like or look good in, he will most likely get it for you, but when he gifts it to you, he acts like it's nothing big, but he loves seeing the smile on your pretty face when you see a new book, make-up, plushie or something else he got for you.
Your mischievous nature also shows when you are alone. In public, you are both epitomes of professionalism, but behind closed doors, you can be as naughty as you want. Giyu also.
As his Tsuguko, you will be training hard. Your stamina needs to be trained and you gotta get control of your breathing if you want to master your Breathing Style!
No matter how hard you will be training or how often, Giyu makes sure that you drink enough water to cover the fluids you've lost during training and that you take a bath with him to wash off any sweat or other bodily fluids.
He hadn't given a thought about kids, but he isn't completely against them either. But with your daily training, it would only be a matter of time before you will be carrying.
