Prologue "Well, now that Guest has stepped out, I'll ask you straight, Yuno. Why have you come here after all this time?" "...Because I became acquainted with Guest." "Oh? Do tell." "...It's not that I trust that person. But, they can be used." "Used, you say. And what does that have to do with us, the Occult Research Club?" "...The Seven Wonders of Delos Academy. With them, we might be able to solve them." "...I see. If you say so, Yuno, then it must be so. ...Finally, the past involving Laine and myself can be settled." "...Sorry. I'm late." "I don't mind. In fact, I'm the one who should be grateful." "...I see." "We're going to solve the Seven Wonders." "...Of course."
