Ollerus

Ollerus (オッレルス) has been called the mage closest to becoming a "Majin" or a "Magic God." He is a mysterious fellow, and one of the strongest characters in the series.

Profile
He first appeared in Volume SS2, going to Academy City in order to put across a point to Academy City's Board of Directors - that if they misuse the "Gemstones" they took in, he will step in to stop them. He is confronted by 9 of the 10 Misaka Sisters remaining in the city, and he manages to defeat them all effortlessly. He is then confronted by Sogiita Gunha, the 7th Level 5. Gunha, after seeing what Ollerus did to the sisters, deems him a threat and attacks. Ollerus then uses the defensive spell called Hliðskjálf in an offensive way, which floors Gunha and knocks him down to the ground. Gunha, however, proceeds to get up without major injuries, and valiantly charges at Ollerus once again, only for the same result to occur. Gunha once again gets up and charges and though the battle cuts off there, we later learn that Ollerus was victorious and Gunha is beaten into the ground. The difference between Gunha and Ollerus' powers weas so large that though Gunha took Ollerus as a serious opponent and went all out, Ollerus was only toying with Gunha.

Ollerus wields the power of the Northern Throne, and his power has been described as incomprehensible and inexplicable. He is currently being pursued by various magical organizations seeking his power, but he has managed to elude all of them with ease. He is in the company of Silvia, who is cruel to him on the surface but still cares for him deep down, and it is heavily implied she is in love with him.

He last appeared in the end of Volume 22, where he rescued a dying Fiamma from the snow. Fiamma, when he realises who is saving him, refers to Otteinus, a tragic magician, as he who became a Majin instead of Ollerus, who saw him claim the title with his very own eyes.

Personality
Ollerus has a kind heart, and he has squandered the once in about 10,000 year chance to become a Majin - one whose's magical powers has reached the level of divinity, and so can bend all natural laws - in order to save a cat. He also destroyed a human trafficking organization and saved 100 children, when he did not need to, and did it knowing full well he would have to face Silvia's wrath.

Abilities
He almost became a Majin, but didn't. It has been stated that he has used the knowledge from a lot of grimoires, though any possible ill effects he suffered is not mentioned. It was said by Silvia that he uses the theory of Hliðskjálf to purify his life force so that it transforms into a special magical power. This just barely allows him to survive the process.

Until now, he showed only one of his abilities in the Volume SS2:
 * Hliðskjálf (北欧王座 （フリズスキャルヴ）), it is his power to change life energy and normal magical power into an unexplainable type of power. The power by its nature cannot be described, can't be explained, and can't be comprehended. Since the power cannot be comprehended, there is no possible defense to stop it according to Ollerus. Also, the actual Hliðskjálf (which is the throne of Odin) doesn't have any offensive function, by forcefully using Hliðskjálf in offense makes his power even more unexplainable. He uses Hliðskjálf due to the fact that his own mana is too special and can't be used with normal magical powers, even if he applied knowledge of various grimoires. In other words, he needs the unexplainable energy to be used up by Hliðskjálf to prevent a build-up of mana inside him and self-destructs.

Quotes

 * (To a child he saved in SS2) “I am glad you adore me, but I didn’t really do anything. Chaining those human traffickers up and making them do manual labor is no different than what they did. That isn’t what I want.”


 * (To Gunha Sogiita in SS2) “No, I really have no guts. But I have my reasons. Unlike you, I have a reason to fight.”


 * (To Gunha Sogiita in SS2) “The most fearsome thing in this world is to be defeated by an attack using an unexplainable power coming from an incomprehensible place while you have no way of thinking up a counter measure. The attack is vague and you cannot assign conditions to it and you don’t even know if there is a direction you can go to avoid it or if you could even avoid it after getting tens of thousands of kilometers away. You now know how horrible that is firsthand.”
