Ultraman Arena: From the Start, I Summon Yeefu to Crush the World

In 2050, the Heavenly Dao descended upon Blue Star and launched the Ultraman Arena. Every nation awakened powerful Giants of Light, champions who represented hope. Once-mighty small nations, led by Sakura Country, were transformed by this upheaval into the world's only superpower. Even the once-dominant Eagle Country couldn't compare. Armed with nearly all the Ultra Warriors from the M78 Nebula, Sakura Country became a world power. The Western nations had only a handful of representatives, able to summon just a few iconic Ultra Warriors. As for Great Xia, its mythology meant it could summon only weak monsters. Luo Yi transmigrated into this world and awakened the Strongest Monster System. On the Ultraman Arena, he summoned the Perfect Life Form, Yapool. “Yoshi! The Sick Man of East Asia actually summoned a white ball?” The next moment, the original Ultraman, summoned by Sakura Country, fired a Specium Ray at it. The Perfect Life Form, who had been dormant as a symbol of opposition to war, awakened under the beam's attack. It returned every move in kind, using their own methods against them. The people of Sakura Country were aghast, while the Western nations trembled in fear. They denounced the Heavenly Dao and Great Xia, calling it cheating.
