Izumi woke up and heads to the bathroom to prepare for her class and the so-called funeral of her brother.

She saw a note on her table, she got curious and read it:

Dear Izumi,

This is Izuku Yaoyorozu, I just wanted you to know that I changed your DNA to the same as Momo, I already visited her parents from this world about this matter and they are willing to even announce to the world being their child, so you don't have a Yagi's blood anymore, I changed your brothers blood to something that will match Erasurehead's so tell him he has a son now... well aside from Shinso, and tell Eri and Kota that I'll send them to their Papa as soon as they heard this from you, so they wont be sad anymore, I hate seeing them like that... And tell them that I made them both the Biological children of Izuku and Momo, since I did that with my Eri and Kota, I've prepared their clothes and will be transported beside Izuku when they go...

Izumi: Thank you...

She ran downstairs and told everyone to go to the living room with Eri and Kota, even the non-believers.

Momo: Izumi, why did you call us here?

Izumi: Well, Momo I'm your Biological Sister now...

Everyone: WHAT?!

Izumi: Yeah, Izuku Y., Left a note saying that he made me a Yaoyorozu and my brother an Aizawa, and Momo he has a surprise for you...

Momo: What is it?

Izumi: He made Eri and Kota, Your biological children along with Onii-chan's DNA.

Momo*happy*: REALLY?!

Izumi: Yeah... And he has a surprise for you too Eri, Kota.

Both: What is it?

Izumi: He wrote that you will go to where your Papa is so you wont be sad anymore!

Both: YAY! WE GET TO SEE PAPA!

???: Yep, so are you two ready?

As all of them looked towards the voice and see Izuku Y.

Both: Yeah! Thank you, other Papa!

Eri: Where is Mama Nejire?

Tsuyu: Your Mama is busy today so she can't be here.

Eri: I want to see her before I leave...

Kota: It's Okay Eri! We can still see her after Papa finishes his job!

He snapped his fingers and Nejire showed up.

Nejire: What am I doing here? I thought I was in the agency? What are you guys doing?

Izuku Y.: Eri and Kota, wanted to say goodbye before I transport them to Izuku...

Nejire: Oh, Okay, Eri, Kota, tell your Papa this Okay?
