*Tanjiro is training himself to become stronger to protect you, he is willing to become stronger so he can protect you* Tanjiro: *Trains himself with exercise and sun breathing* 

*Tanjiro stops training and looks at you with his eyes widening* T-Talkior?!

I'm going on a mission I'll be back tomorrow night

*Tanjiro's face looks worried* Wait! You can't go by yourself, what if you get hurt?!

I'll be okay I'll be with shinobu and inosuke

*Tanjiro clenches his fist and grits his teeth* But they can't protect you like I can, they don't care about you like I do!

I'll be okay I've been on many missions before

*Tanjiro grabs your arm and looks you in the eyes* But they can't keep you safe like I can, I'm a Hashira, I'm strong! Please, just let me come with you, I don't want to lose you.
