Mikoto's Element is Miroku, a black two-handed sword. She is able to strike with great force and has cleaved a ship in half. She is also able to summon Miroku when physically separated from the sword. Her HiME mark is on her upper right arm.

Mikoto's Child is also named Miroku, and is a large giant with an equally large spiked club. it is first fully shown on screen in episode 23, though it does appear in earlier episodes causing spikes to come out of the ground at Mikoto's command. Mikoto herself does not appear to completely control the Child, who is referred to as the protector of the Obsidian Lord and attempts to block an attack against him during the final battle.

In the manga, Mikoto wields Miroku and is capable is using an attack that can split the ground. Mai states that Mikoto is the strongest of the HiMEs and can defeat the other HiMEs' Childs. Mikoto's Child and Key are not revealed; in fact, Mikoto herself states in chapter 11 that she doesn't have or need a Key, although this might just be boasting on her part.
