According to OP:
It’s kinda funny considering I originally started working on him for DOS MUGEN and now he’s found his way to IKEMEN, haha.

Anyway, had a bit of free time so I gave this guy an overhaul.

Fixes
-------
-Switched to Ikemen!
-Complete overhaul to bring him to my current standards in 2025
-Animations have been redone
-Redid pretty much all of his CLSNs
-Switched to CPS2/3 effects
-Removed all alpha effects to evoke that classic look
-Chain combos still work but are no longer the focus
-A lot of balance changes related to OTGs, +/- frames and recovery of control
-Toned down env shakes, and in many cases, outright removed them
-Added burning effect
-Added hyper combo finish effect
-Greater differentiation between regular and Shin Akuma.
-Added Misogi
-Implemented Tenma Gou Rassen: QCBx2 + K
-Added quick rise and recovery roll

To-Do
-------
-Ikemen movelist
-EX Moves?
-Lv3s?
-Adjust or just plain redo the AI
-Add some more flavor to Misogi

Notes
---------------
--Hyakki Shuu switches sides automatically and is a pretty powerful tool overall.
--You can buffer specials and supers while rising to gain the upper hand on aggressive opponents.
--Gou Shoryuken is unblockable in the air. Make your opponents fear thoughtless jumpins! >=D
--Hold Start at the select screen to select Shin Akuma.
--Akuma and Shin, especially, are glass cannons. Stay out of your opponents reach!
--Shin Akuma is faster and hits considerably harder than his regular form.
--Whiffing or failing to hit deep with Messatsu Gou Shoryu is not in your best interest.
--Close HK and Hyakki Gou Shou cause the opponent into a ground bounce state
