The final act of "Destruction" Chapter was finished. The song magic succeeded; Ion and others stopped Nelo from going back. Awaken Ion, taking a firm stand that she had never did, made a negotiation with PLASMA. (Maybe her subconsciousness was coming out at that time.) Nelo's words are a hint to Ar nosurge.
Nelo:
I understood one thing by this incident.
Both I and you never be able to go back unless we have some existence who can overlook our own world.
教会にて、またニヤニヤ会話がwでもここで「あなたはどう思ってる？」と聞かれた時の選択肢が、どちらもはぐらかしているのでイオンがちょっとがっかりしてました。端末、しっかりしろ！
At the church, we had a grinning conversation again. However, I made Ion disappointed a little because my choices of answer when she asked me "How do you think about it?" were both dodging her question. C'mon, the unit!
Ion:
I can never practice continence which I have to dispose this happiness...
