There will be 18+ stuff and harem trope in the book
IZUKU in the story will still retain OFA along with the other quirks involved
Also IZUKU will actually be a lot more OP before he got OFA due to him training like the HANMA-KURE family and Toji Fushiguro
When he goes to TFPverse, He will still retain all of the perks he's gained but on 50% of it
In the TFPverse, MECH will be more calculative and cunning in their approach towards the Cybertronians
There will be a lot of Alt modes for IZUKU along with the Bayberse template of the KSIBOTS as a source of inspiration
BTW: EILL NEED HELP FROM U GUYS SO PLZ HELP A BROTHER OUT
