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

really hard boss, few demon can withstand its attack. we only need 3 demon that have full rakukaja buff. oh yeah i realise that level actually matter on nocturne. demon that level below 10 is already cannot be used because it can't withstand attack and deal poor damage.
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.
he can actually run out of mp probably useful if we don't have any rakukaja on our demon...
