Late in the series, for an unknown reason (at the time), Yuga takes a sudden interest in Izuku, and begins to act rather strangely around/towards him, something that does not go unnoticed by fellow peers, more specifically Izuku’s friends, and more importantly, Izuku himself, although he doesn’t seem to think too much of it at the very start.
At the end of one class period, Izuku mutters “I’m starving!” At this, Yuga creeps eerily close to him, and with a blank smile, stuffs a piece of cheese into his mouth, saying “Here, have some cheese ~” This causes Izuku to startle, and exclaim that Yuga scared/surprised (depending on translation) him, and question, “Cheese?” Yuga gives a brief on that specific cheese, before simply looking off, to Izuku’s confusion.
That night, Izuku wakes to a sudden noise outside his room. As he looks up from his bed to investigate, he sees a shadowed Yuga on his deck, peeking through the curtain before swiftly disappearing, a grim expression on his face all the while. Izuku thinks to himself about how creepy that was, and wonders if he should go check on Yuga, or see what he was up to. Upon reaching his deck, he notices a plate of small cheeses laid out to spell “I know ☆” ( “知っている ☆”). He, once again startles at this, likely unsettled about what it could be that Yuga “knows” (such as his feelings for Ochako or the secret behind his quirk).
When he next sees Yuga, who simply winks at him and whispers “Surprise!”, which unnerves Izuku once more. He nervously smiles at him before heading to his desk. He thinks about why Yuga has started acting out like this towards him, as they’d never interacted much prior, then deciding that he should leave the issue unaddressed, as Yuga must have a reason for doing so. Later, during a training exercise, Yuga calls Izuku’s attention, as to have him watch his new “ultimate” move, which he dubs ‘Navel Buffet Laser’. However, this takes a lot out of Yuga, which Izuku notices, then taking him aside to let him take a break from training. As they walk, Izuku takes the opportunity to question why Yuga had been acting strangely. Yuga then reveals that he’d noticed that Izuku’s quirk was rather ill-suited to his body, in the same way that Yuga’s was to his, saying that this gave them a sort of ‘invisible bond’. He then adds that he’d noticed Izuku feeling a bit stressed since his work studies, and was, as Izuku realized, attempting to cheer him up. This brings a grin to Izuku’s face, and its later stated that he and Yuga became fast friends after this, to both of their happiness.
As the two only began to interact notably quite late in the series, leaving time for alternate ships for the Yuga and Izuku to take rise (such as MinaYama or TodoDeku), DekuYama is not too popular in the MHA/BNHA fandom, and is left a ‘rare-pair’, albeit one with slightly more traction than most. Additionally, the interaction they did have was interpreted in several ways outside of what Yuga told Izuku, one of them being a sort of sudden ‘crush’ on him, leading to a desire to get closer. However, there is no true evidence for this in the end.
- In one official analysis book, a page lists Izuku and Yuga both under the category of ‘Gag Characters’.
