Haruto Tokishima

Piloting Skills: He has good piloting skills. This is shown off in the first episode where he took down multiple units of full-fledged soldiers who carry more battle experience than him.
Immortality: Upon being injected with an unknown substance when entering the Valvrave I, he would become immortal, as he has lived even under the most fatal of injuries.
Bodyjacking: Another effect of the unknown substance allows him to hijack bodies by directly biting onto another person's bare skin. Those he switches with becoming unconscious, like his body. He also obtains any abilities that their body has, such as good aiming and piloting skills as shown when he took L-Elf's body.
Rune Absorption: As a Magius, Haruto is able to absorb runes from humans by biting directly onto their bare skin. An ominous green light is produced when absorbing runes. This ability is necessary in order to power the Valvraves.
Rune Manipulation: Haruto is able to manipulate the runes, although crudely, like Cain Dressel, who projected a sphere of light around him when showing his powers for the first time, in a similar manner and send L-Elf flying over a very short distance. Haruto was also able to power a signal flare using this ability.
