Heartwarming / Togainu no Chi

  • Pretty much all the good endings save for Shiki's count as this, with both Akira and whoever he's with escaping Toshima.
    • And even Shiki's becomes this if you listen to the end of the Drama CD which hints that he's waking up.
  • Keisuke recovering from his Line addiction and reconciling with Akira.
  • Akira telling Rin he'd never betray him.
  • Getting to see Nano finally smile in his ending.
