Thirty-Year-Old Social Animal Is Reborn as a Baby, and Everyone Is Bound at the Beginning

A social animal who died suddenly was reborn as a baby, bound to a system of three times a day of random information. He did not skip a grade and fully experienced his school days. The business landscape was already mature in high school. When four heroines with intertwined fates appeared at the same time, what he had to do was to complete the transformation from "a person who uses intelligence" to a "person who controls his destiny" under the dual pressure of Shura field and business war.
