SMT : Nocturne HD Remaster - Sui-ki (Low Level, No Fusion, No Shop, No Comp, No Mutation, Hard)

same strat as fuu-ki battle but he is more phys oriented and his damage is not really that strong.
The Rule is :
No Fusion (NF) - Self Explanatory, I must Finish the game without fusing any Demon
No Shop - i can't access/buy magatama that available on shop and i can't restock item with help from shop, I need to get all of item by any other means except Shop.
No Comp - No Compendium meaning i can't save any demon. it makes sure i only have few Demon that i can use.
No Mutation - i mean skill mutation, i'm still allowed to evolve demon. i can't change any skill demon for recording simplicity.
Low Level - I play on base nocturne that doesn't have Fiends, Dante/Raidou, and TDE boss. because i don't know if any of this restriction is even possible so i decide to get additional EXP from Oni Side Quest, and from demon that guarding treasure. aside from that i only get exp from mandatory battle.
doesn't show in the video but glacial blast can make mc freeze and he can instant kill mc. that happen to me once because i don't equip null ice magatama for learning media sake. but that just prove how effective this strategy is.
