optimistic go-getter
mischievous schemer
sharp-witted
boldly action-oriented
Shinpei Sakamoto is Junichi's indispensable best friend and the mastermind behind the group's many unconventional plans to escape their shared predicament. Cheerful and unapologetically frank about his interests in girls, he constantly devises outlandish yet creative schemes, ultimately playing a pivotal behind-the-scenes role in nudging Junichi toward confessing his feelings to Yame. Despite his carefree and somewhat eccentric personality—including a particular fondness for feet—he proves surprisingly diligent and dependable whenever work responsibilities are on the line.
