Ending Fatigue: Chapter 8 is long, very long, and consists of no less than three major battles that are lengthy in their own rights with the first one of them being the most difficult. Players who initially stated their interests in obtaining every ending or playing New Game+ said they changed their minds after realizing they'd have to do Chapter 8 again every time.
Hilarious in Hindsight: Just try and play the part in So Long, My Love where the Star Division members are confronted by their dark selves without thinking of Persona 4.
Jerkass Woobie: Geminine. She is violent, arrogant and an overall jerkass who is more than willing to indulge in Disproportionate Retribution, to say nothing of her attempt at Split-Personality Takeover... And also a completely broken individual whose very existence was unknown to everyone, including her own parents. The one person to realize she and Gemini were different identities was her beloved master, whose murder at the hands of Ranmaru marks her Start of Darkness. Geminine breaks down in tears after Shinjiro makes her see how far she has fallen, and, by the end of the chapter, she decides not to interfere with Gemini's life again.

That One Level: The first fight of chapter 8 brings with it a huge Difficulty Spike for the endgame. You have to defend the Ahab's engines from wave after wave of enemies until it rises to a certain altitude. There's very little room for error as said engines don't have much health at all and since it's a combination of both land and flight combat, you're going to have to spread your units very thin.
