Murakami is Shikanosuke's friend and his former partner when he played doubles in the tennis club. He is big and macho but easily gets sentimental. His family owns the alcohol business Murakami Liquor, and he is always seen wearing Murakami Liquor T-shirts. He likes to join in on Go games, and is also in the Go club. While he could not join d2b, he teaches the d2b members about what punk rock is.

After graduation, he forms HAPPY CYCLE MANIA and plays guitar.
