YOU DONT HAVE TO READ THIS!! its only to give context in case you're confused, but if you dont want to than yeah.
TL;DR: He has the gnosis and acts like Makoto, and he has friends💪
This is basically just me explaining my headcanons just in case you're confused on whats happening.
1. i feel like hed take after Makoto rather than than Ei, id feel like hed be more peaceful bc he has the gnosis/heart, and idk if this is true or not but if Scaramouche was made while Makoto was alive i feel like he would spend a lot of time with Makoto
2. he would have long hair, i feel like hed be made with long hair and stuff yk and Makoto/Beelzebub would style it, braide it, or put it in a ponytail
3. hed def be hired by Yae, bc in the actual lore hes said to be pretty/handsome, so Yae would hire him or something and girls would be swooning over him (as myself except im not a girl)
4. i think the Kaedehara clan would have less beef with the shogun, as we learned from one event Scaramouche legit killed Kazuhas grandfather(i think) but i feel like bc he took after Makoto he would try and make peace with them rather than Beelzebub having beef with the clan
5. (ties in with 4th) after Makotos death Beelzebub has always pictured him as Makoto and although she never gave him too much power she always gets his opinions on decisions she would make (ties in with 6 too, ties up with 4 bc its like explaining abt how raiden wouldnt make bad decisions)
6. raiden shogun (aka the one we had to kill) wouldve never existed, many things happened bc of Makotos death but Scara could make up for that soooo yeah
7 hed probably get along with Sara, Kazuha, Thoma, Yoimiya, and the Kamisato clan, i feel like he wpuld get close to Sara bc of raiden, and i feel like hed always be thankful for the kaedehara clans bladework, and i just think when he goes out in public with Ei he socializes with the Kamisato clan and Yoimiya
-would pribably talk to sara about cool his "mom" (beelzebub) is
-check up on Kazuha and even join him on a few trips
-got along with Thoma Ayaka and Ayato bc tri commision stuff and had a game of chess with Ayato which lasted 3 hours (ended in a tie)
-would adore Yoimiyas fireworks so much, and probably talk to her about her and her dad
this is gonna be the most random hc but i feel like non abandoned Kunikuzushi would learn how to wood carve, and make little wooden decorations and Kazuha would make some of the blades for his wood carving even tho he doesnt rlly know how too and he would use them bc he felt bad hes make Sara a raiden shogun carving and Ayato a homemade chessboard and a little fish decoration for Yoimiya
Baal will probably be referred to as Ei/Baal for the fanfic and Scaramouche will probably be referred to as Kunikuzushi for part of it, even tho its not his original name but his original name isnt here soo Kunikuzushi it is
hell just be referred to Kunikuzushi in any formal way/with Ei
and will probably be referred to Scaramouche with his friends
now that thats out of the way time for fanfic
