Level 5

Level 5 (超能力者(レベル5)) is the highest current Level that espers have achieved in Academy City. Only seven people out of the 1.8 million students in Academy City have been given this rank, which shows how difficult it is to reach.

All the currently known Level 5 espers, have nicknames attributed to them that are related to their powers or are actually their powers. Most egregiously, Accelerator is known only by his nickname.

Characteristics
Level 5s are espers that hold tremendous power, and are far above any other person with powers the same as they are. The seven who have achieved Level 5 are generally considered monsters, as they are capable of fighting alone against a military force on equal terms. They are so powerful that their primary powers are banned in the Daihaseisai.

Furthermore, as power development is part of Academy City's curriculum, the strongest of Academy City's espers, such as the level 5s, are also honor students. This is displayed by Mikoto, who has enrolled in Tokiwadai Middle School, and is one of its top students, as well as Accelerator, who has consistently displayed awesome feats of ability that require immense calculation.

The ranking of a level 5 is dependent on the esper's usefulness in achieving SYSTEM.

Personality
A particular object of notability of all the Level 5 Espers is a recurring instance of mental instability, be it comedic or serious. Mikoto, the first Level 5 seen in the series, has a comedic obsession with defeating Kamijou Touma, although she has been referred to as the most sane of all the Level 5s. Sogiita Gunha believes himself to be an ally of justice and purposely acts in accordance of superheroes in fiction. Accelerator, Kakine Teitoku, Mugino Shizuri, and Shokuhou Misaki all demonstrate more sociopathic or psychopathic tendencies with the willingness to hurt people on whim, though this may be more related to their background more than anything else.

Due to this, only Mikoto is the one apparently competent enough to be used as a marketing mascot or demonstrator for Academy City. Even then, it is not unheard of for any of the Level 5s to be requested for demonstration.

Addition to this, many of the Level 5s are not on good terms with each other.
