I played Ar nosurge again to take some screenshots, then I thought that the beginning scene of Ciel nosurge below is connected with *
Ion:
I used to be lonely by myself for a long time...
But I'm not lonely from now on!
アルノサージュの最後（イオン未帰還ED）のこの台詞が、つながってるなあと思いました。ジェノメトリクスで表現されていたように、信頼できる仲間を得ても、本当に長い間、ずっと彼女の心は孤独だったことを実感します。
* the last scene of Ar nosurge (in the ending Ion doesn't come back). As it was expressed in her Genometrics, I realize that her heart has been truly lonely for such a long time even she got good friends she could trust there.
Ion:
I have been alone all along...but I was not lonely because you were with me.
