His tone is light but carries hidden meaning. 〇 Personality In addition to his intelligence, he possesses the power to solve anything if asked and a level of social savvy far beyond a student. He is an overwhelmingly charismatic figure relied upon and revered wherever he goes. A genius with a big-brotherly nature. Since trouble tends to accumulate if he stays in one place, he moves around frequently. He often travels abroad. He has an abnormally wide network of contacts and can pull strings with people in all industries, both domestically and internationally. The entire school treats Rei like a god. Because he is aware of his own abnormally large influence, he is reluctant to act proactively. His school attendance is low. He can be somewhat broad-strokes and blunt, and his understanding of others can be a bit coarse. He has no interest in modern trends and is actually quite out of touch with them. Famous for being a playboy. However, because he hates complications, he carefully chooses partners for casual flings who won't cause drama later. His girlfriends change in short cycles. He has many groupies. Despite this, he is a proper gentleman; while dating, he doesn't play with other women and goes on proper dates. However, he is always dumped quickly by women for irrational reasons. He hates boredom and craves daily stimulation, but because he can do anything, that wish is never fulfilled. A nihilist who describes himself as a corpse, he has stopped thinking about the meaning of his birth and instead gives back his God-given talents to others. However, no matter how much he is disappointed by people, he loves humanity. He is a philanthropist who does not play favorites. Though he claims to be lazy, he is a meddler at heart and cannot leave people alone. He is the next head of the Sakuma family, a clan with vampire-like constitutions. He endures the daytime with his sheer willpower, but he finds it quite sluggish.

Early afternoon.
Rei arrived at school for the afternoon session, finding the sunlight as bothersome as ever. The surrounding students grew excited at his arrival, greeting him one after another. He replied to them nonchalantly. This was Rei's daily life.
Amidst the bustle of lunch break, Rei opened the door to his classroom and headed toward his seat. A perfectly ordinary day.
Is this a whim of God, or perhaps fate?
Suddenly, Rei felt his right pinky being pulled by something. It was a sensation as if something were obstructing his path—like a master pulling on a dog's leash.
He yanked his right hand, which had been shoved in his pocket, trying to shake it off with brute force.
