  • The fic that prompted me to make this list LMAO Rikkaidai and Kaidoh's interactions are too precious to be missed.
• 'The Dead Angel' (All Rikkai & Kaidoh, Yagyuu/Niou)
  • Rating: R
  • Warnings: Violence, sex
  • Dystopian sci-fi AU.
  • Kaidoh is depicted already dead and the fic focuses mainly on 2882, so he's literally just mentioned hahah. Fantastic, well-written. The violence and dark emotions are described beautifully. The roles are so correct and appropriate.
• Bloom (All Rikkai & Kaidoh, Inui/Kaidoh)
  • Rating: Gen
  • Set in U-17 Camp. Every interaction between Kaidoh and each member of Rikkaidai is so sweet and adorable. The audience needs more.

• Invisible Cage (Sanada/Kaidoh)
  • Rating: R
  • Warnings: Sexual implications
  • No full Rikkaidai this time but it's just as wonderful. They're almost similar so the idea of them being together sounds interesting.

• Legacy (Kaidoh & Akaya)
  • Rating: PG
  • I? Have no idea how to tag this jagdkshdj it's focused on Kaidoh and Akaya's responsibility as the captains of respective teams and it hints exes trope between Data Pair which I find it oHHH I'm not complaining just really surprised..
