Netsuki is a former slave from the Kirika Empire's slave army who joined Parabellum after being freed by Rou.


Netsuki appears as a young man with short red hair and short horns on his head.


Netsuki was initially very prideful and arrogant, especially about his abilities. He grew more humble after seeing the great difference in strength between himself and Rou.

He never forgets a grudge, and will hold on to it until he's satisfied.


Despite being first seen in Day 81, his name is not known until Day 110. Even so, he is dubbed as Fire Lord-kun, or simply Fire-kun.

He joined Parabellum after being freed from the Kirika Empire's slave army.
After seeing that Parabellum was only led by an Ogre (Ogarou) he decided along with Fuuki and probably Genki to rebel and take the command. But they were easily beaten...
Rou decided to use his Ogre Orb to make some experiments.

Later, he traveled with Rou to Trient and Osvel along with Fuuki and Genki.

During a friendly competition with adventurers (with Rou charging admission fees), 1,000 gold coins were offered as reward to anyone that could defeat him.

On Day 280 he receives a Demigod's Divine Protection and ranks up to 【Blaze Lord - Variant】, awakening as one of the of the 18 Demon Warlords and holding the title of [Purgatory Sword].

It is later known that the Wolf Hero was the one who turned him into a slave.
He takes his revenge during the Holy War by killing him but refused his sacred treasure.


Netsuki is skilled in the use of a sword and can emit flames under his control.

He received a new ability ever since Ranking Up, called 【Purgatory Demon Sword】. His Demon Jewel (Ogre Orb), that becomes a flamberge gushing flames when released, now becomes gigantic when 【Purgatory Demon Sword】 is used, and he enters a state where the flames he is clad in are strengthened. Because he becomes just like a miniature sun in such a condition, if one doesn't have 【Tolerance】 or 【Complete Tolerance】, it seems like it would be difficult to approach first.


He forms a good trio with Fuuki and Genki but only him managed to become a Demon Warlord.
