Since we are in the middle of the usj this part is gonna be non canon to the story since it would be weird for everyone to stop attacking each other and celebrate his birthday especially since the villains hate him. So yeah non canon but it will happen I'm gonna say after their first school year. Enjoy. Multiple pictures at the end. Searched up his birthday just to find one ended up finding ten 😅.  Oh and since this takes place after when I tend for Izuku and Ochako to get together they are together in this chapter.

3rd POV
"come on mom we got to get this ready before he gets home" said Izuku rushing through stores to find things for his fathers birthday. "I'm hurrying Izu I can't walk as fast as you can." Inko said trying to follow Izuku. It was Izuku's fathers birthday today and they're trying to plan a surprise party at the dorms. They were lucky Nezu not only let the class leave to shop for gifts but to allow Toshinori's wife come to the dorms to celebrate with them.

After everyone got what they wanted to get the class had met up and went back to the dorms. Ochako and Izuku holding hands on the way there. (gotta put the fluff in somewhere.) The plan is for Nezu to give all might another lecture like how when the usj was occurring while the class decorates the dorms and tries to make a birthday cake and hopefully not burn the entire building down. Luckily with Sato that doesn't happen often in the sweets aspect.

Everyone was helping even Bakugou. The presents were already wrapped and everyone split in half. (I want to say that I actually plotted who was doing what using the seating chart. So yeah I'll ad the pic after.) Izuku, Ochako, Toru, Shouji, Jirou, Kaminari, Mina, Iida, Momo and Todoroki were on deco and Aoyama, Ojiro, Bakugou, Kirishima, Sero, Tsu, Mineta, (purposely put him on the team that has the least female members for obvious reasons.) Koda, Tokoyami, and Sato are on baking.

Eventually everything was finished and as if on schedule Aizawa (he was there to celebrate but was just sleeping during the set up. Then again when isn't he.) got a call from Nezu saying he's on his way. The class got into hiding positions turned the lights off and waited for All Might to show up. It didn't take long before they could hear him humming to himself the song he had sung for Inko when she found out she was pregnant with Izuku. Inko smiled softly at the memory. Toshi opened the door and was confused. "Huh? That's weird I could've sworn it wouldn't take the kids this long to get groceries. Oh well." He said as he turned the light on and as he did everyone jumped out and yelled "SURPRISE! HAPPY BIRTHDAY ALL MIGHT/ DAD/ TOSHI!" All might was taken aback by the this. He had no idea that they would remember his birthday let alone set all this up. 'Wait is that why Nezu made the lecture so long? Did he do that to bye them time?' He thought but he didn't care. He smiled and said "Thank you everyone you didn't have to do this." "Nonsense. You were the number one hero and symbol of peace for ages. It's the least we can do. Besides Izuku suggested it." Said Ochako while inturn made her Deku blush of embarrassment of being called out for thinking of the idea. "I just thought it would be good to finally celebrate your birthday after years of not being able to due to well you know." Izuku said scratching the back of his neck with a visible blush that out does the color of Kirishima's hair.

The day went on with fun laughter telling stories and after 17 years of not playing guitar or singing the song Toshi decided to play his and Inko's song that he wrote. After asking Jirou to borrow her acoustic. To say everyone was shocked that he could play was and understatement but that didn't matter. All that mattered was that everyone was having fun. Until at some point something unexpected happened.

All Might was talking with Inko having a great time with his family friends and students but then he felt a tug on his pant leg. He looked down to see Eri staring at him a bit nervous. "Um excuse me Mr. All Might sir but daddy has told me that you were always a great influence and inspiration to him. I wanted to thank you for helping daddy want to become a hero. I don't think I would be as happy as I am now with mommy and daddy if it weren't for your influence on my daddy. Thank you so much for everything and happy birthday." She had said a smile plastered on her face unfaltering. Toshi has tears of happiness on the corner of his eyes. He picked Eri up and hugged her. "You are very welcome young Eri. If I could turn back time I'd do it all again. Also just call me pop pop I am you grandfather after all." Toshi said. "I love you pop pop." "I love you too Eri."everyone awwed and cooed at the scene with Ochako and Izuku crying at what their adoptive daughter had just done. The rest of the day was fun and normal and eventually everyone was asleep.

To explain the long pause I did that to make you guys think that something bad happened but it was just really something adorable. Now I was originally going to do the usj part 2 but I kept putting it off and had no idea on how to write it so now CrazyCollector is the one set to write the chapter and I have no doubt that it will be fantastic. Anyways picture time.
