Heartwarming / Ciel nosurge

• The extra scenario "Sisterly love? Paternal love?" is aptly named. It shows glimpses of Renall during the first three chapters and how she privately feels about Ion. We see her resolutely cheering for Ion after the disaster at the start of the Succession Trials, gushing about Ion's success in the Big Flowers event (even purchasing a cake to celebrate!) worrying about her during the climax on the Dream Sphere and then making sure she sees Ion's dance at the Ra Ciela Starlight event. Despite appearances in the main storyline, Ion was correct when she insisted that Renall was a Cool Big Sis to her.
• This part when you deliver a You Are Not Alone speech through clickable dialogues to Ion when she's depressed over the revelations during the Chapter 7.
• The Valentine date event. Even if you don't have anyone else, Ion will still be your Valentine.
• If you receive the True Ending for Earthes and Ion in Ar Nosurge and you have linked your PSN accounts between it and Ciel Nosurge, you'll receive in Gust's internal e-mail box a voice mail from Ion along with a picture◊ showing that yes, she has indeed made it home. Looks like your bonds aren't so star-crossed after all.
  • It also crosses over into the downloadable epilogue story for the second light novel, and the voice message included in the Ethestron Genometric Concert compilation: They confirm once again that Nei arrived safe and sound at her world, and she is working her hardest in her Earth's equivalent of the CERN in order to cross dimensions and meet you again.
