Sogiita Gunha

Sogiita Gunha (削板 軍覇) is introduced in Volume SS2 and is the 7th Level 5 Academy City student thus making him one of the most powerful espers in the city. Despite being a level 5, the underlying nature of his ability unknown. His rank as the 7th level 5 may not be reflective of his true capabilities since no one understands his power. He is nicknamed both Attack Crash (念動砲弾), after his signature attack.

Personality
His personality is not unlike Kamijou Touma, though he is considered hot-blooded and dives into problems headfirst without considering the consequences as shown through the encounter between Gunha and Ollerus, where he misunderstood Ollerus' intentions.

He is also somewhat dense in certain situations, as shown in the Toaru Jihanki no Sonzai Shoumei light novel the first thing after being shot by Mikoto's railgun is commenting that gaming tokens aren't supposed to be taken outside arcades, and that he'll go back with her to return it and apologize.

He also appears to have a habit of giving completely impossible explanations for the nature of his abilities. For example, his explanation for what he does when he executes Attack Crash is that he creates an unstable field of psychokinesis in front of him and destroys it by providing a stimulus from his fist, thus causing an explosive aftereffect for some distance, something which a nearby student in the Power Development Curriculum for telekinesis says is impossible. Also, he explains his Aurora Guard as him lifting Earth's electromagnetic field and using it to defend against Electricity-based attacks, another impossible phenomenon.

Appearance
Gunha can easily be recognized by his modified white uniform. He wears his jacket over his shoulders as a make-shift cape. He also wears a white headband on his forehead to match his overall style. But the most noticeable part of his ensemble is his Rising Sun shirt, which aptly matches his personality.

Gunha has black and somewhat spiky windswept hair.

An alternate drawing of Gunha has him wearing a sweater vest, a collared shirt, and hair that is swept/combed down. He also looks calm and discreet unlike his usual flamboyant and hot-blooded self. This version reflects one of the possible alternate characterisations for Gunha before his character was finalized by the author.

Background
Little is known as of yet what Gunha's background is, though it is confirmed that he is one of the few pure Gemstones in the world and is also the greatest.

Toaru Kagaku no Railgun
Gunha himself does not appear in the Toaru Kagaku no Railgun manga but is seen in one of the collections of memories that formed the AIM Burst where he was referred by a man who used the Level-Upper, Gunha is the catalyst for the man to use the Level-Upper after witnessing Gunha using his Amazing Punch on a bunch of thugs, the man later dresses-up like Gunha after recovering from the coma induced by the Level-Upper but is told that he doesn't look good in it.

He appears in the Railgun Sidestory Toaru Jihanki no Fanfare and fights Mikoto, and demonstrates that he is able to catch her Railgun at 30% power in between his teeth. He has also managed to withstand various attacks like twin chainsaw-like swords of iron sand and a lightning strike from the sky Mikoto have used to attack him.

Toaru Majutsu no Index
In the sidestories Gunha ended up in a fight with some thugs on patrol, and later fought against a very powerful magician known as Ollerus due to a misunderstanding. Even with the MISAKA Clones fighting alongside him, they and Gunha were quickly defeated.

Toaru Jihanki no Sonzai Shoumei
Gunha is featured in the min-novel by ''[http://en.wikipedia.org/wiki/Baccano! Baccano!] and [http://en.wikipedia.org/wiki/Durarara!! Durarara!!]'' author, Narita Ryogho.

Abilities
His ability displays a variety of effects which maybe the reason why Academy City cannot comprehend it fully, these effects include:
 * Explosion - Create a strange explosion around him that throws people away
 * Indifference to pain and Invulnerability - Not wholy but feels prickly pain when hurt and will not receive any serious damage when he is shot or pierced in the heart. He also is able to catch Mikoto's Railgun shot with the teeth.
 * Enhanced Speed - He can perform physical combat at twice the speed of sound.
 * Pseudo-teleport - He is also capable of "teleport", displayed in a little fight against Kuroko.
 * Forcefield Projection - Cover his whole body with unknown forcefield.
 * Attack Crash - Gunha's sure-kill technique. He yells 'Amazing Punch' ( すごいパーンチ, Sugoi Punch ) when executing it.
 * Aurora Guard - He can bring up a part of Earth's electromagnetism field by using "telekinesis" to act as a shield against Mikoto Misaka's most powerful lighting strike. Stated to be impossible by physics and cannot possibly be the explanation in the light novels, so the exact mechanics of how he can stop Mikoto's electric attacks is unknown.

Quotes

 * (To Ollerus in SS2) “I’ll show you what true guts are!! You don’t need some great reason. A man who isn’t twisted or rotten, even if he’s a complete stranger, can stand up for some injured girls!!”
