During the USJ attack, the group splitted out from the other students from the class and so the four were ready for fight them, but then All Might arrives the place in the right moment and so dealt with LoV by himself. All Might then gets cornered by Shigaraki and Kurogiri, moments later Midoriya jumps to the scene for preventing All Might get killed by Shigaraki by using his quirk, which didn't manage to control it all yet in that time, and before noticing, he was already in LoV's hand, with him almost dying while Bakugo, Todoroki, and Kirishima were contemplating the scene. But then the other teachers arrive just in time thanks to Iida saving Izuku and so LoV fled away from the place with Kurogiri's help before they could get absorbed by Thirteen.
During the Hideout Raid Arc, Kirishima and Todoroki are seen together walking to the hospital looking for Midoriya, which had a mental breakdown because of Bakugo's kidnapping by LoV, and when they finally got to see him with the small amount of students reunited there, Todoroki told Midoriya about Bakugo's situation of the case. Midoriya then finally regains his consciousness by Todoroki's words and Kirishima then cheers Midoriya up by saying that they would save him along with him too. Throughout the Bakugo's rescue mission, Midoriya creates a plan in which Kirishima and Todoroki would be involved, which consisted on Todoroki impulsing Midoriya, Iida, and Kirishima with his ice so with Midoriya's quirk they would impulse themselves to the air and so catching Bakugo in midair. Midoriya then picks Kirishima for rescuing Bakugo, since he was the first friend Bakugo did when he got into U.A, and so, they made on rescuing him thanks to Midoriya's plan and with Bakugo's support in the plan.
While the group don't all interact together because Todoroki uses to be more with Midoriya and Bakugo with Kirishima, Izuku and Eijiro are the ones who had changed Todoroki and Bakugo respectively, with Midoriya making Todoroki accept his left side which succeeded during the Sports Festival, and Kirishima supporting and respecting Bakugo, but telling him that he had to change too. While Kirishima and Izuku are cheerful, Bakugo and Todoroki tend have a rude personality sometimes, paralleling their personalities with their best friends.
The ship sailed as result of the most popular ships (TodoDeku and KiriBaku) being mixed in one, although those who don't like both TodoDeku and KiriBaku would prefer TodoBaku and KiriDeku or BakuDeku and TodoKiri while being mixed in one ship. They're usually portrayed together in original artworks. Fans would also prefer adding Shinso in the ship because of Midoriya's kindness and rivalry towards him, creating ShinTodoBakuKiriDeku. Some take it to the next level and add Uraraka, creating TodoKiriShinBakuDekuraka.
In artworks, the group are seen hanging out together to different places, or doing different activities all together, they also tend to wingman the other ship which is in TodoDeku's case wingmanning KiriBaku, and in other times the other way around.
On AO3 the ship currently has 310 fanfics.
