Personality

 * As a kid - He was rowdy, and violent because of the discrimination he got as an astral-user.
 * Present/ as a teenager -

As a kid
Satoru was an orphan and lived in the orphanage called Fuuran. He was rowdy and had violent tendencies as a kid because of the discrimination made against him as an astral user. He was jealous of non-astral users because of the normal life they had (family and friends).

One day, Satoru was roaming the streets when he found two adults bullying an astral user, and a young girl at that. Thinking to himself that he cannot ignore astral-users being discriminated, he intervened by taunting the two male adults, eventually leading to a fight. This fight led to the two adults bleeding, Satoru breaking one of his arms because of his improper use of his astral ability, the police getting involved, and Satoru being avoided in the orphanage. During the common route, it was eventually revealed that it was Hazuki that Satoru saved when they were both children.

This fight also led to Ryuunosuke investigating about Satoru, and eventually adopting him when Ryuunosuke found out about his past. After getting adopted by Ryuunosuke, Satoru's personality slowly changed to a more soft demeanor. As Satoru's father is part of the SFD, Satoru insisted to join the SFD to put his astral ability to good use. Ryuunosuke was initially against the idea, but eventually let Satoru join.

Present Day
As a member of the SFD, Satoru is tasked to handle missions that revolves around preventing astral-related crimes. He is assigned a code name of Levy 6 for operations together with his sister, Nanami, as Levy 9. Satoru was first seen talking with Nanami in one of their missions during the summer.

Astral Ability
Satoru's astral ability is neural manipulation. It allows the user to manipulate his own brainpower to perform various tasks. Feats accomplished by neural manipulation:


 * Physical Enhancement - Satoru increases his physical capabilities by allowing it to be at maximum output. It similar to a person being able to freely enter and exit an "adrenaline-rush" state. During Satoru's enrollment, he covered up his actual astral ability as super strength by carrying Mayu Shikibe with one hand.
 * Eidetic Memory - By temporarily boosting his brainpower, he is able to have photographic memory for a short period of time. Satoru uses this when he needs to memorize an abundant amount of information as fast as possible.
 * Super senses - Temporarily boosts the effectiveness of his 5 senses and his reflex/reaction time.
 * Sight - see better in the dark, see better detail in long distances, see objects usually invisible to the naked eye
 * This can be seen when Satoru was able to see the water threads laid out by Hazuki Nijouin around the school.
 * Hearing - increases his auditory range to hear decibels usually unheard by normal humans, and to hear more from farther distances
 * This can be seen when Satoru was able to hear Ayase Mitsukasa's voice when she was attacked.

Drawbacks
Satoru noted that his power boost is dangerous because it damages his body in prolonged used. Since he's not capable of feeling pain while at this state, he must be conscious of how long he has been using power boost. While in this state, only the pain caused by the enhancement is nullified, and other physical trauma inflicted by an external influence will be felt by Satoru. Satoru often requires healing through Nanami's astral ability after using this skill. He is also often exercising or building his muscles so his body takes less burden when using physical enhancement.

Other Abilities/Non-Astral Abilities

 * Invisibility - Satoru's suit allows him to go invisible at will.
