Shiki Tademaru

Species: Half-human/Half-Arachne

Up until he came to Inugami's detective agency and before his uncle took care of him, he lived in Kinshi-Go in the Gunma Prefecture with his mother. Shiki initially comes off as a bully, holding his age of one year over Kabane as an authority, and telling the other boy they aren't friends because they're both hybrids. But this is shown to only be a facade, as he shows surprise at Kabane never having had pizza, and laughing when the other first had trouble trying it. But as Akira says, he's only self-conscious due to the fact another hybrid sits under the same roof as him. When on a job, he can see things in a calm and cautious manner. He is also able to judge and react to things in a fast manner, like using his thread to protect him and Akira from Kon's attacks. However, he can also be seen with a short temper. When faced with intimidating enemies, he has the tendency to freeze up but always manages to defeat his enemy.
