What was the event that caused the amnesia 40 years before?
It’s hinted that an event caused everyone in Paradigm City to lose their memories. Every so often the city resets itself, but it’s also explained that a worldwide catastrophe is the cause of the amnesia, and that reality in the series is a virtual reality that resets because of Angel. Also, there is speculation that Roger Smith aka The Negotiator is a robot, but it is never confirmed.

Which girl did the main character wind up with? And did his parents ever approve of his sister’s eroge collection?
The main character, Kyosuke, basically enters a harem situation with several girls in his life, including his sister, Kirino. All squickiness aside about the potential incest angle, the situation with the girls proves a point about siblings growing apart and then coming together again with maturity. As a side note, their parents find out that Kirino is an otaku and collects eroge but Kyosuke manages to defuse the situation and save Kirino’s eroge collection. The main question there, however, is did her parents ever realize that the eroge collection was, in fact, Kirino’s and that she still had it?

Did Spike actually die at the end?
Speculation has run rampant that Spike Spiegel, the main character of Cowboy Bebop, didn’t die in the final duel that he has with antagonist/main rival Vicious. According to some fans, Spike managed to survive his gunshot wounds after being shot down in the climactic clash at the Vicious’ headquarters and lived to see another bounty. Personally, we don’t believe so. He was very clearly shown to be dead as well as Vicious and the woman they were fighting for. Spike knew the battle was going to end one way and there was no coming back to Jet and the Bebop.

Who is Suyin Beifong’s father? Who is the mother of Zuko’s daughter?
Popular characters from Avatar: The Last Airbender Toph Beifong and Fire Lord Zuko each present some interesting questions in relation to their future offspring. It’s stated that Toph has two children that you see in the series, Republic City Chief of Police Lin Beifong and Zaofu matriarch Suyin Beifong. The women mention separately that they have different fathers that neither knew. While Lin’s father is briefly talked about, Suyin’s is not. Zuko, on the other hand, is shown to be in a relationship with Mai at the end of The Last Airbender and to have a daughter who takes on the Fire Lord throne in Legend of Korra. This begs the question of who is the mother of his daughter, Mai or someone else? These questions are never answered.

Does Aizen actually carry out the full 20,000-year sentence?
While we do know that Sosuke Aizen is sentenced to his long stay in prison at the end of his arc in Bleach, we don’t know if he will ever carry out the full sentence. It’s probable that the villain will, given that souls do not die or age like normal in Soul Society and he was empowered by the HÅgyoku, which renders the person infused with it effectively immortal. Even though he was let out of prison in the final act of Bleach, it’s implied that he was effectively held to serve the entire sentence.
