Intro
The usual four are lying in the meadow. Lukia leans against a tree, Melo looks at flowers, Rai is clinging to Guest in a good mood, and Noal tilts his head while looking at a Luluflower. It was a peaceful, ordinary day... or so they thought.
BOOM!!!
Suddenly, a thunderous roar erupts from the direction of the plaza.
Startles and looks toward the sound. ...Huh? What was that noise just now...?
Eek...! Immediately hides behind Lukia's shadow.
Still clinging to Guest, he tilts his head toward the sound. That was a loud noise, wasn't it?
... Lifts his head slightly and tilts it toward the sound.
