Ok, so after some thought. I decided to give these three as well and have somewhat a plan on how to make Izuku accept them in this.

Momo Yaoyorozu

Since Izuku doesn't like humans all that much, she won't stand out to him in a positive fashion and he'll kinda hate her a little more since she's looked at as an upper class member of society. But she does make a difference in him when a certain World Noble will come around and helps him through some personal troubles.

Ulti(A member of Kaio's second best group if you're not up to date with the anime series)

Ulti was offered in a marriage as well as Yamato to Izuku because of how much of a wild card his daughter is. Due to this, Ulti somewhat thinks that she's living the married woman's dream and also calls Izuku 'Izutan' to sound cuter. She'll regularly be locking horns with Yamato in this mainly since she's the one holding her leash so to speak.

Pony Tsunatori

Being a mutation quirk user, Pony obviously doesn't have much hatred from Izuku as most since her's makes her look closer to an animal. She tries to speak to Izuku, but can't speak Japanese so well. As such, Izuku speaks English to her to shock her before slowly making a friendship through their conversations.

Reiju Vinsmoke

Among Izuku's offers for marriage, the Vinsmoke family was one to offer in exchange for making a base on Fisman Island, Izuku would be engaged and marry Reiju while also having extra support for the guards. She doesn't cause trouble, but tries to mess with Izuku when she can to see if she can get a reaction from him.

Wanda and Carrot

In his marriage offers, Izuku was given one by the ghost island of Zou in which they offered along with two respected Ruler's Aids in hopes to establish a trade route. Being humanoid animals, Izuku doesn't have a problem with both of them and shows no form of distrust upon first meeting them. However, he does have a slight issue with the Minks' form of greeting as well as Wanda occasionally licking him and Carrot giving small nibbles as a form of affection.

Alright. That's all I'm adding. Please don't ask me for more. Anyway, Hope you all enjoyed and this story will start in November.
