Riku Rei summons Suigin after her father, Riku Yuuki dies, and hands him something that Yuuki apparently left for him. Though he is hesitant, Suigin accepts the item, which happens to be a specialized console to play the new game “Grave Buster.” On the console, Riku Yuuki left Suigin a message and one billion in inheritance and tells him to protect Riku Rei.
Happiness fell into my 
lap way too suddenly!
!وقعت السّعادة في حضني بشكلٍ مفاجئ
Das Glück ist mir zu plötzlich
in den Schoß gesprungen!
¡La felicidad llegó a mí muy de repente!
¡La felicidad llegó a mí muy de repente!
C’est trop de bonheur d’un coup !
Quale felicità è piovuta
improvvisamente dal cielo!
A felicidade chegou rápido demais!
Счастье так внезапно попало мне в руки!
