SO i don't think this song is like sung from midoriya’s pov, but is sung to him by everyone who cares about him (all might, inko, the izucrew, class 1-a in general, etc)
because izuku’s whole Issue is that he has no self-preservation. like i know we make jokes abt this but dude is seriously near actively suicidal with how negligent he is to his own health and safety. he’s so determined to be a hero that he doesn't care what it costs him -- as long as he's the one paying the price, that is (biggest example of this is his arms and how he’s literally punched the use out of them at 15)
he also hates bringing up his problems and how he feels. we see this implicitly w the fact that he’s never confronted bakugou abt their past and explicitly w the scene where he has a breakdown and iida and todoroki calm him down, but he says “heroes don't cry” and hides his face, etc
so i think this song is his loved ones coming together to be there for him and get it thro his thick skull that he doesn't need to save the world before he can save himself and i'm so fuckign emo so let's just jump into it
here’s the song: https://www.youtube.com/watch?v=Us82yZTkO6g&feature=youtu.be
i referenced a comment on the youtube video for the lyrics hhh. it should be near the top but if not uhh good luck trying to double-check me sorry i couldn't provide a more concrete source this time djkfjkf
ok let's go
“you're not alone, there’s no doubt your gift isn’t futile to be”
okay so let’s get to the point first of all; all of midoriya’s loved ones Need him to know that he is not alone. midoriya probably has a mindset where he’s used to thinking he’s alone, due to how he grew up friendless and antagonized, and i have no doubt whatsoever that he hasn’t actually completely shrugged this mindset off. so his loved ones need him to know that he’s not alone anymore and they are here for him dammit so he doesn’t need to shoulder everything by himself
his “gift” is not one for all but his kindness and love for the world. it “isn’t futile to be” because midoriya is obviously going to become a hero and thus, put those traits into good use. he’s going to be an inspiration for more than his physical strength; his most powerful aspects are his gentleness and compassion
“if we’ll be united, we’re stronger together”
this kinda goes back to the “you're not alone” line. his loved ones have assured him that he’ll be a great hero on his own with the “no doubt your gift isn’t futile to be” line, but they’re letting him know that he can be “stronger” w his loved ones by his side; he doesn’t need to lone-wolf it. you're stronger when you're fighting alongside your loved ones while simultaneously fighting for them, right? so they're basically introducing that concept to our green bean here
“we always have the high hope”
“high hope” = high ground if u will. they have the advantage in any battle if they have midoriya’s brand of determination and spirit. also midoriya does not let go of hope like at all. even after that awful as hell childhood, he still clung to hope and he still dared to dream and that’s really important. this is his loved ones acknowledging that, but probably inko in particular bc she’s been there in his life for every single hardship
“not all for one but one for all”
this is definitely a toshinori-exclusive line. it's not subtle at all that this line is abt the quirk and the villain, but what i think it’s saying exactly is that the burden that one for all brings its users does not need to be solely on midoriya’s shoulders alone (all for one); he has loved ones and allies and coworkers and teachers that are there for him and will guide him and support him, thus sharing the burden (one for all). midoriya doesn’t need to save the world himself
“don't worry ‘bout a thing”
the classic comfort token(tm). no but i feel like this is his loved ones kinda saying “don't worry [about things you can't control because you're only human].” bc obviously midoriya is human and also himself so he’s going to worry, but they're here soothing his anxiety and irrational fears, as they have already addressed his more rational fears in earlier lyrics
“we’ll reach out to you/even if it’s a harder way/it’s plain to see the reason why/oh that’s all because of the mighty heart”
midoriya’s loved ones are promising him here that they are always going to do their best to support and love him adequately. they know he has a habit of hiding his feelings and other problems and that that could lead to some issues, hence the “even if it’s a harder way”, but they're going to keep loving him anyway
why? well, “it’s plain to see the reason why oh that’s all because of the mighty heart.” midoriya’s heart and soul are so pure and so good and just completely full of kind intentions. all midoriya has ever wanted to do was, to quote his own words, “become a hero and save people with a smile.” he loves so fiercely and so quickly and it has changed all of the lives of everyone he’s met, particularly his loved ones. like toshinori would be dead w/o midoriya, as would probably iida and todoroki (stain arc and quirk complications each). they love midoriya and all that he has done for them, and so it is more than worth it to be there for him in return
“remember that it’s just natural that we’ll be there if you need help”
they are saying that, as midoriya’s loved ones, as people who love him, it’s only natural that they care for him and want to see him happy, just like he does them. they're kinda using any excuses he could come up about “not deserving their support” against him. they're letting him know they're there for him and again, most importantly, that he does not have to deal with ofa and all of his other burdens alone
“far across the distance/rest assured that our faith won’t die”
this distance is both physical and emotional. inko in particular is distanced physically, now that izuku is living at the dorms, but she is still going to be there for him. emotionally, the distance is the blocks midoriya puts up to keep from acknowledging his seriously negative feelings, at least from others. however, like they say in the song, “rest assured that our faith won’t die”; they’re not going to give up, bc midoriya wouldn’t give up. they believe in him and love him sm
“you know we apt to sacrifice ourselves/whatever they may say”
his friends/toshinori in particular are saying this line. hero work is a dangerous job, obviously, and they all signed themselves up to be public servants in such a dangerous field, meaning its kinda their job to sacrifice themselves if needed. however, this is again letting midoriya know he’s not alone in this risk, as “we apt to sacrifice ourselves”
the “whatever they may say” bit is abt media and the public. they will sing midoriya’s praises and some may criticize him, but they're letting him know that they don't know him like they do. they don't love him like they do. but midoriya’s friends and toshinori will bear the burden of media together as they are all heroes. they wont leave him alone in any of this
chorus once more (”it’s plain...won’t die”)
anyway i’m crying midoriya loves so much and he is loved so much in return thank you and goodnight
