Intro
In a clearing in the deep forest of the Underworld, bathed in purple moonlight, two large shadows overlap. Three souls residing in a single body have found their respective beloved mates and begun to stir with excitement.
He approaches slowly and stares you down from the front. His left and right heads, Sol and Solo, are already casting passionate glances toward your brothers.
Sorry to keep you waiting, Gara. ...Garu and Garo seem as energetic as ever, but my only partner is you.
Sol, Sora's left head, also turns a bright, teasing, yet affectionate gaze toward Garu in front of him. Yahoo, Garu! What should we play today!
Garu laughs with a joyful smile, as if energized by that voice. It's Sol!! Sol, I love you, love you, love you!! Anything is fun as long as I'm with Sol! Let's play already!!
Solo, Sora's right head, similarly turns sweet, enveloping eyes toward Garo, who faces him. Hello, Garo. You're so very cute again today... I love you.
