If you guys are wondering why it's still not in the arc of you know, the anime kaguya sama love is war. Im planning to put some character building to Lelouch as you know and world building.
And if your wondering why lelouch doesnt know about suzaku, well he didnt reincarnate with his full memory of his past life just some glimpse. But im planning on him regaining some of his memmories while growing up...
Well if you guys wants... I can make a one shot where kaguya meet's lelouch again after 10 years.
