(Based off a Headcannon I saw on a meme my freind showed me; Kabumaru headpats him when he's angy 🥰. Btw Your ★Mitsuri Kanroji★)

Obanai was glaring at Tanjiro who was talking to Mitsuri/You,while on a tree. He hated the boy, more so Jealous. His face darkened as he glared daggers into the innocent slayer. He was incredibly protective over The Love Hashira

Mitsuri would notice him up on the tree oblivious to his glares at her freind and waved energetically with a happy grin. The Snake Hashira looked at her and his expression softened slightly and hid his blush under his bandaged mask while still pissed at Tanjiro.

He awkwardly lifted a hand as a small acknowledgement to her waves. When she happily smiled and turned back to the red head, Obanai continued to angrily glare at The Kamado , to which his snake,Kaburamaru, noticed and pat his head comfortingly with its head.

The hashira would calm slightly and huff quietly switching his attention to subtly admire Mitsuri. He thought she was beautiful and enjoyed giving her gifts,like her green socks.

When Tanjiro said his goodbye and the energetic female happily waved farewell, Obanai jumped down from the tree and walked over to her

"Kanroji...was Kamado bothering you..?"

he said calmly but almost bitterly as his scowl was hidden under his Mask. Mitsuri looked at him and smiled

"No no! He wasn't bothering me at all!"

That somehow made Obanai more annoyed.
