Secrets Discovered

Introductions

Hi, your Author Chan is here again :) So this story is a bit hard to understand so let's start. There are too many crossovers, be warned.

Hinata Family:

Mafuyu(Hinata) Sato (20):
(From Given) Mafuyu's father got arrested as you know in the anime and his mom died because of a plane crash when she was going to work. Mafuyu was 16 then and Uenoyama wanted to offer Mafuyu to live together but he couldn't since he already have so many siblings and not much money. He brought his phone, Yuki's guitar, and everything he needed then walked out of the house. Hinata's mother found him on the streets a week later and adopted him(Shoyo was 12 at that time). Now, he was in the band Given and was back from a world tour.

Hinata Shoyo (16):
(From Haikyuu) Canon

Hinata Emma (12):
(From TPN x MHA/BNHA AU) When Emma was 9 (Shoyo was 13), she and the others got saved by Pro Heroes(All Might, Aizawa, Hawks, Recovery Girl, and Mirko) and some heroes in training (Deku, Kirishima, Uraraka, Shinso, and Big Three) came (Bakugou, Todoroki, and Endeavor aren't exactly good with kids). After Mission Eri but before Nighteye's death, Deku asked if more kids need help. Nighteye used foresight on him and told him that children in Grace Field House are in danger. They helped all of the children escape and rescued the ones in different farms as well. Isabella escaped and Connie didn't die.

Hinata Natsu (5): (From Haikyuu) Canon

Kageyama Family:

Uenoyama(mother's name and Kageyama is his father's name) Ritsuka (20):
(From Given but he doesn't have an older sister in this)Step-brother and the oldest of the family. His mother died from childbirth and his father remarried. Now, he was back from the world tour with his band to visit his family.

Nanase(mother's name) Haruka (18):
(From Free!) The second oldest in the family. Kageyama is originally his last name but he changed it because he doesn't like his father because he forced him out of the water all the time. (It doesn't make sense but who cares)

Kuroo Tetsurō (18):
(From Haikyuu) He changed his name to Kuroo because he doesn't want to attract any attention as his brother Kageyama Tobio was featured in Volleyball Weekly(I made up the name but Kageyama is in a lot of magazines). He wanted to be recognized as Kageyama Tetsurō or rather Kuroo Tetsurō, not Kageyama's brother and he attended Nekoma.

Kageyama Tobio (16): (From Haikyuu) Canon.

Chinen Miya (13):
(From Sk8 to Infinity) He is their cousin and was treated as a brother as he always comes over. He taught Tobio and Shoyo how to skate and call them slime chan and slime san.

Kageyama Ray (12):
(From TPN x MHA/BNHA AU) Same as Emma.

Midorima's family:

Midorima Shintaro (17): (From Kuroko no Basuke) Canon.

Yamaguchi(Midorima) Tadashi: (From Haikyuu) Changes the last name because he didn't want to be recognised as the green miracle's brother. Also, he moved to the Miyagi Prefecture to go to Karasuno.

Midorima Gilda (12):
(From TPN x MHA/BNHA AU) Same as Emma.

Nikiforov's family (Katsuki Yuri x Nikiforov Victor):

Sugawara(Nikiforov) Koushi (18): (From Haikyuu) Was told to change his last name by his parents as they don't want press following their son.

Haiba(Nikiforov) Lev (16):
(From Haikyuu) Same as Suga.

Kuroko Tetsuya (16):
(From Kuroko no Basuke) Adopted.

Nikiforov Norman (12):
(From TPN x MHA/BNHA AU) Same as Emma.

Shiota Nagisa (10):
(From Assassination Classroom) Adopted.

Heartfilia Family:

Heartfilia Lucy (20):
(From Fairy Tail) Canon.

Yachi Hitoka (16):
(From Haikyuu) Same as Lucy but changed the last name to avoid being recognized.

Heartfilia Connie (7):
(From TPN x MHA/BNHA AU) Same as Emma but now lives with Yachi and sometimes Lucy in Fairy Tail.

Extra information: Haruki from Given is Asahi's cousin. Akihiko from Given is Tsukishima's cousin from the father's side and Midorima is Tsukishima's cousin from the mother's side. Which makes Yamaguchi and Tsukishima cousins. All these people know each other since the oldest meet and brought their siblings. The trio from TPN reunited with Gilda and Connie.
