Each of the monsters in this archetype is named after a character from the classic Chinese Novel Romance of the Three Kingdoms. The theme's name itself seems to be reference to 戦火senka (the fires/horrors of war) and 中華chūka (the Japanese spelling of a poetic name for China meaning "The Central Flower"), resulting in something similar to "Warring Flower".
In addition, the attributes reference the story. Monsters with WATER attributes were from the Wu Kingdom, where the kingdom was best known to be surrounded by rivers and lakes. Monsters with WIND attributes were from the Shu Kingdom. Monsters with FIRE attributes were from the Wei Kingdom. During the Battle of the Red Cliff, Shu strategist Zhuge Liang was infamous for "borrowing the wind" and winning the war.
The archetype focus on summoning more than 1 "Ancient Warrior" as some monsters can only activate their effect if another "Ancient Warrior" activates their effect. The Continuous Spell, "Ancient Warriors Saga - Sun-Liu Alliance" also encourage playing "Ancient Warriors" of multiple attributes.
