William Svalbard

His personality contrasts sharply with Selma's: he is nervous, diplomatic, and concerned about the political consequences. He is always apologizing to other countries for Selma's aggressive and deceitful behavior.
Selma treats him like her servant or subordinate. She bosses him around, gets angry if he suggests she might lose, and literally leads him around by the nose. He's the perfect example of Selma's reputation as a "spoiled princess" or arrogant woman.
After the incident with France, William arrives flustered, apologizes to the other World-End Heroes, and berates Selma for creating a diplomatic disaster. She angrily replies, "Are you saying I'm going to lose?" and he falls silent.
When Selma decides to go see Aiden (who was injured in the Chinese zone), she drags him along without asking permission. He follows her resignedly.

We, the Heroes of the End of the World, are considered a new branch of humanity, a species that emerged thanks to a phenomenon called Polyphenism. It is this process that allowed us to develop unique cells called Theseus Cells.

These cells allow us to survive in lethal concentrations of carbon dioxide without suffering any ill effects. And what's more… they give us superhuman abilities ranging from manipulating the weather to altering the composition of our own bodies.

Over time, we Heroes of the End of the World became the military core of our nations. Not by choice, but because Gaia outlawed weapons of mass destruction—missiles, nukes, everything—to prevent wars that would devastate the planet.
Because of this, a country without a Hero of the End of the World is practically defenseless if its hero leaves for another nation. Therefore, the more heroes a country has, the more invincible it is.
In total, there are 17 Heroes of the End of the World, including one who works directly for Gaia. The list is as follows:

Albie Hiddleston, United Kingdom

Hasuichi Nishizono, Japan

Aiden D. Adams, United States

Hui Xiyi, China

Namir Shaaban, Egypt

Luca Akehurst, Australia

Diana Kissinger, Canada

Narsidurgu, Mongolia

Lily of the Valley, France

Selma Jorgensen, Norway

Luong Tho, Vietnam

Mikhail Asimov, Russia

Rafael Gutiérrez, Brazil

Imena Eneramo, Nigeria

Maisie Mayberry, India

Eliseo Cavalieri, Italy

Gopher, the hero of Gaia

Because of what we are… our Theseus Cells can recombine our body's properties when they become active. This is called Cellular Property Recombination, and it's what allows us to change, adapt, and… well, do the things we do.
