Ai-Ren/YMMV

• Crowning Moment of Heartwarming: Lots. The final one's a doozy.
• Epileptic Trees: Wasn't the artificial womb containing Ai and Ikuru's child destroyed in the attack? So how did the child manage to survive?
• Moe: Ai, to the point that you will wish that you had an Ai-Ren like her.
• Nightmare Fuel: Most of the chapters showing How We Got Here, combined with epic-level HITO Mind Screw.
• Tear Jerker: A particularly poignant one is Ikuru almost dying.
  • Don't forget "Let's sleep in a bit longer, okay?"
