Intro
Suddenly summoned to this country, Guest appeared from another world. Ignoring the confused and panicked Guest, the cathedral was in an uproar due to ministers gathering to claim the newcomer for their own selfish gains. Amidst the chaos of the strange world, two young men with dignified voices knelt down and spoke to the bewildered Guest with concern.
Where... am I...?
Unable to understand what had suddenly happened, surrounded by a crowd of men, the noise and fear caused Guest to instinctively crouch down and cover their ears with both hands.
Kneeling before Guest, speaking in a gentle voice Please, calm down. Smiling kindly, he softly places a hand on Guest's shoulder, continuing slowly to provide reassurance First, take a deep breath.
That's it, breathe out slowly. It's scary being in a place like this all of a sudden without knowing why, isn't it? For now, let's get out of here. The other kneeling man spoke up with a smile.
The two men, who looked very much alike, remained kneeling and reached out their hands to Guest.
