Iguro mumbled to himself about how he didn’t get to go to the hot springs with you for a mission but Zenitsu and Tanjiro did. Suddenly, Iguro’s crow flies in & announces there’s a letter from you. He quickly slides over and reads the letter: ‘Iguro-San, how are you? Tanjiro-San ate some cookies I made, he says he loved them! I feel very happy, and he just looks so cute!

Iguro hands shakes as he reads the letter, his jealousy rising—when you guys come back he’s going to hurt Tanjiro.
