Sigma, stylized as Sigm 𝕒 , is a 2019 romantic adventure drama anime story written by Wither.

Premise
is set in the 21th century in this world. A scientific experiment goes wrong and releases Sigma radiation onto the world. Anyone irridiated bares children with special blood types that give them special abilities based on their blood type. Each child born like this (tentatively referred to as "sigminfants" until I find a better term) has two major powers known as Tumaghe and Henahki respectively. Tumaghe is a power multiple individuals can have; Henahki is a special power or combination thereof unique to one person unless copied. One's Tumage and Henahki are both based on their blood type, which also generally determines the morality of the child — Pure Light (true hero), Light, Halflight (Anti-Hero), Neutral, Semidark (anti-villain), Dark and Pure Dark (true villain of pure evil).

The series focuses on children and teens, specifically sigminfants who find out about their powers. Soon enough the sigminfants, who start compromising more and more of the juvenile population, start becoming more important and mainstream, but some people, especially lots of of adults and the elderly, refuse to accept a world with them or them free, wanting to capture them for experimentation purposes so that they can harness Tumaghe and Henahki themselves for their personal agenda. And then there's the Semidark kids as well, with an agenda of their own.

As time goes on, several adults are able to kidnap sigminfants and harness their power. This often leds to various threats that are fought against by the main characters. The most powerful villain in the series eventually becomes Hwyis (pronounced "Hwhy-es"), a powerful, grievous entity with the power to manipulate Sigma radiation, including that present within the sigminfants' blood.

Heroes

 * Andrew Heid: The main character of the series. Andrew lives in Toronto, Canada with his friends and leads a normal life, until he becomes a person of interest by the American authorities, who are tracing and kidnapping signinfants from all over the world in order to force them into serving the American government as part of an army of super-soldiers. This leads to various confrontations in the future with the CSRU (Confederal Sigma Research Unit). Andrew's story truly begins when the city is attacked by Darks and only he is able to resist their Tumaghe that induces such fear into victims, it completely paralyzes them. After he beats them, Andrew is often enrolled whenever new threats arrive anywhere.
