Buddhist Temple Alien Arc

Soon after her first appearance, she has sex with Kurono Kei. This does not appear to be for any particular reason (aside from the fact that he asked and she stated that he was cute).

Final moments

In the manga

After Kurono is injured and lying helpless, Sei speaks to him.

  • Sei: "Why did you ask me to have sex with you? Maybe... you kinda liked me? Maybe?"
  • Kurono: "Not really. Just... you looked like you'd let me. That's all. I just... wanted to do it. With anyone."
  • Sei: "If I take it down... do you think... you'd kinda fall in love with me?"
  • Kurono: "What? Stupid Bitch run!" [1]

In the Anime

After the majority of the Gantz Team fall to the Buddha Temple boss Sei realizes that Kurono does not feel the same way about her - instead he thinks more of the deceased Kishimoto than her. Seeing the boss approach, she asks Kurono if he would love her if she defeated the enemy. Once she receives her answer, she fights against it both solo and with her bare fists. Although Sei is able to injure the alien she is unable to defeat it and she dies defending Kurono.

Oni Alien Arc

When Kaze asks Kurono who he wishes to revive, Kurono briefly deliberates between her and Kishimoto. In the end, he chooses neither and revives Nishi Joichiro.
