I made this on ibis paint and am posting it here

My man is going through it
But anyways meet Naoko Ashino my beautiful boy who went through it as a kid and still is cause he got isekai
Just some context he's mute and can't show emotions and has a blank face constantly but can show them through his shirt that will show different images to show what he's feeling on the inside and changes colors to tell his mood
He can talk to his sword (that is a mini god that will grow more power because it has a mouth that eats the dead and grows powerful) the sword communicate to him telepathically and that's how they both speak to each other and the sword can relate whatever Naoko is thinking to other people with its mouth
