Chapter 12 is the first time we see Heavy Tank Doumeki, when they bust into a Matsubara hangout to ask/accuse about the shooting. Doumeki is livid that they would put three bullets in his boss and it shows while Yashiro looks on respectfully

More Heavy Tank Doumeki in Chapter 16 for reasons I feel we all agree on. Inami is an asshole and I could watch Doumeki beat him up all day all day

On to Chapter 20, where they chase down Chestnut & Co to find Nanahara. Here, Doumeki breaks one of Chestnut's arms and his hair floof as he runs is asgjkahjafs

And Chapter 29, when Doumeki oversleeps and finds Chestnut outside picking up Yashiro's car. But Chestnut mouths off again and Doumeki breaks his other arm
