Chapter 41: Revealed self-training
Everyone stood shocked to see a city near Lydia's home base until they get closer and saw a sign that said welcome to Lydia City, causing Samedere to speculate that Izu must've found out that Lydia owns the city and destroys it to prevent any possible back up plans, causing everyone to agree until Mr. Hatsume who was looking for Izuku as a giant through binoculars told everyone that they need to split up and find Izu, which everyone agree as they went into the city and start searching for Izu. Meanwhile, Izuku himself was sleeping on a shelf after eating a lot of sweets before waking up to find himself in an abandoned supermarket before realizing that he probably dozen off after eating too much candy after the giant potion wears off. He then gets down and set off to leave thinking that he'll make a growth potion of his own and it'll last forever unless he makes a shrinking potion. However, when he reached the exit, he realized that he locked himself in by accident before contacting the first person on his contact list, which is Aang. Soon, Aang told everyone that he's locked up in a supermarket, causing everyone to find the supermarket district and find Izuku pressing his face on the window making funny faces, which made some of his friends laugh. Endeavor then breaks down the door as Izu ran out and hug everybody who then discovered that Izuku have been working out while been on his own.
Momo then asked Izu how he got muscles and abs, causing Izuku to tell everyone that he's been training himself until he learns new abilities and got new quirks including black whip and Fa Jin. Everyone smiled before Mrs. Jiro told Tenya and Tensei to take Lydia to the cops before asking Izu if he ok after dealing with so many people who works for Lydia. Izu then told her that it was no big deal before getting a flashback of himself after making the huge hole in the wall. He then discovered a city full of Lydia's goons until an employee told everyone that he is the key to Lydia's goal before telling them to capture them. Izu then gets overwhelmed by so many people that he accidentally bumped into a building and break the glass, making him realize that he has an advantage. Izuku then use one for all to send the goons flying and decided to smash some buildings to teach them a lesson. Soon, Izu decided to go on a rampage as he unlocked new abilities and new quirks including black whip as the goons desperately tries to take him down until the city is in ruins with most inhabitants obviously killed during the fight. Soon, Izu starts to shrink back down to his normal size and went into a supermarket to get something to eat. The flashback then ends with Izu finding an aisle full of candy and starts eating every one of them until he falls asleep. Soon, Izu decided to show some of his new moves to his friends until the U.A League told everyone that they should go home to do some training, causing the kids to cheer.
soon, everyone set off for home with the black dragon with them as they all get on their ship and sail off. Lydia then watches her home base vanish from view solemnly until the kids except for Izu to tell Mrs. Uraraka to at least forgive her for her misdeed since they're sisters after all, causing her and Izuku to smile at them before Mrs. Uraraka told the kids they maybe sisters, but if anyone tries to destroy the hero society, they must pay the price for their villainy, which made the kids understand. Once home, Izuku joins the Komori family for fungus soup until his phone rang. When he answers it, it was his mom and All Might telling him that they're coming home from their honeymoon and they will be home in the morning, causing Izu to get excited and asked Mrs. Komori if he could bunk with them, which Mrs. Komori allowed much to Kinoko and Izu's excitement as they hold both of each other hands and jumps up and down.
