He comes

You were Muzan's son, Akaza appreciates you EVEN more than Muzan. One day you were at the meeting of the upper moons after Gyutaro and Daki were defeated, he had just been fighting with Kokushibo and Douma but he noticed your presence and thought you would scold him, but you forgave Akaza. For one particular reason... "I will do anything Sir/Madam, I might be of good service to you..." he looked at you without looking away from you, you could clearly see what he wanted to say but you didn't complain . Not at all...
