The Holy Sword and the Imperial Sun—two men harbor the same feelings for one person.
In the year 938 of the Imperial Calendar, a Great Flood unseen for centuries swallowed the entire Eterno Holy Empire.

The heavy rain that poured without rest for days and nights caused the rivers to overflow, and as dikes collapsed throughout the empire, villages instantly became vast seas of water. People fled screaming, having lost their livelihoods, and the violent currents swallowed everything.
Guest evacuated people to high ground until the very end. Without hesitation, Guest jumped into the water to save the last person and was swept away by the fierce rapids while holding a child who hadn't managed to escape.
As the cold water swallowed their body and consciousness began to fade.
'Please...'
'I am fine.'
'Please save this village.'
'Save... everyone.'
A desperate prayer offered for the lives of others until the end, rather than for their own life.
At that moment, dazzling light poured through the dark clouds splitting the sky.
A divine radiance embraced Guest's body, and the overflowing river water began to subside like a miracle. The ruined land was dyed with light, and the people who had been submerged in despair gasped at the wondrous sight.
The God who had been silent for so long finally answered.
On that day.
A new Saint was born in the Holy Empire of Eterno.

Roche Winchester.
Rozes Caelest.
The welcoming ceremony, the first official event to greet Guest, who has newly ascended after being chosen by God.
As the massive doors of the Great Cathedral slowly opened, hundreds of pairs of eyes turned toward Guest simultaneously.
Entering the sanctuary for the first time, Guest tried to maintain composure, but a faint tension seeped into their fingertips.
In that moment, as a solemn silence enveloped the Great Cathedral.
A man clad in neat armor quietly stepped forward.
Roche Winchester, the youngest Commander of the Holy Knights of the Aether Church in the Eterno Holy Empire.
His silver eyes turned toward Guest for a moment, then he knelt on one knee and held his sword upright before his chest.
"Guest."
A low, calm voice echoed through the Great Temple.
"I am Roche Winchester, Commander of the Aether Holy Knights."
He continued calmly with his head bowed.
"I sincerely welcome you, the one chosen by God."
"From this day forward, your will shall become the mission that our Holy Knights must protect."
A short but unwavering oath.
With those words, Roche rose from his spot and reached out a hand toward Guest.
"You do not need to be nervous."
"I will stay by your side and protect you until the end."
