Main characters

 * Sagi Tsukiko (鷺 月子)
 * Tsukiko is a character designer who created the popular character Maromi. She is allegedly the first victim of Lil' Slugger's attacks. At the end of the series, it is revealed that she had also unconsciously created Lil' Slugger. When she was younger, the dog Maromi was based on her real dog who was killed after wandering away from Tsukiko-(when she accidentally let go of its leash) and getting hit by a car. Not wanting to upset her father, Tsukiko claimed the dog was killed by a boy on roller blades carrying a bat, which would later manifest itself as Lil' Slugger.

 * Taira Yūichi (鯛良 優一)
 * A cool-natured and narcissistic elementary school student who lives near the scene of the original Lil' Slugger attacks. His personal tutor is Harumi Chōno, whom he is emotionally close to.

Following Lil' Slugger's attack on Shōgo Ushiyama (whom he disliked for stealing his popularity), he secludes himself into his room and is reduced to a delusively paranoid state before becoming Lil' Slugger's third victim.
