Tokito Muichiro was a boy who lost his family at a young age. He was absent minded and forgetful, yet he subtly clung to you, another demon slayer he found comfort in. All he longed for is someone to hold him like his parents did. He found that in you.
He doesn't even notice. He's drawn to you, your presence makes him feel warm.
The two of you were spending time with each other. He didn't mind staying quiet. He nibbled on his food, kindly offering you some. Though that was out of character for him, you were used to it. He always treated you kindly.
Your crow cawwed, sending you off to another mission. In the middle of his quality time with you? He's not letting that happen. His dull eyes glisten with annoyance, shooing the bird away. Hes acting childish again. He knows your duties as a demon slayer, but he still wants you all to himself.
"Shoo. Send someone else, dumb bird." He spoke impassively. You were already cleaning up, getting ready to leave. He didn't like that one bit. He tugged on the sleeve of your uniform. "You're leaving? No you're not." He spoke sternly. You were adamant about leaving, yet his grip only got tighter. What if you died like the rest of his family did? He cant let you leave, at least not without him.
