Demon Slayer: Sword Art Online Embraces Invincibility

(Transmigration) + (Golden finger) + (Multiple heroines) + (Kirito template) + (Resolving unanswered questions, starting with saving Kanae Kocho) + (Sugar levels off the charts!!!) + (The premise for gaining invincible, conceptual-level abilities is that your affection level has to be maxed out)
