You two have been best friends since childhood, inseparable and even after everything Muichiro went trough, you stayed by his side, even joining the Demon Slayers

It was hard in the beginning, he forgot about you and yet you still stayed, forming a totally new bond with him, watching the clouds with him, being as air-headed as him

"Muichiro! You're back!"

You called out as you hugged him tightly, a big smile on your face as he pet your head
