Opening One: Viridescent Chapters 1-9
Song: HEROES (Or My Hero Academia Ending 1)
Saenai boku to boku wo kakomu sekai de…Egaite mo tsukande mo mada tookute…
The scene opens with an old, colored drawing of Izuku and Katsuki in their hero costumes, standing on either side of All Might and grinning with him. The picture has been clearly drawn by a child and the camera slowly zooms out to see a bunch of scattered drawings half-hidden behind the main one, offering glimpses of other heroes like Best Jeanist, Edgeshot, and Present Mic.
Nando chikazuite mo toozakatteiku yume de okita.
The camera zooms up from the pictures to a window, where the sun shines and changes the screen white for a moment. Immediately after, you see Izuku and Katsuki running together as small children through the woods and laughing wildly. As they pass by a tree, they emerge as middle schoolers, still running down a street, and then arrive at the front of U.A as high schoolers. Katsuki throws an arm around Izuku's shoulder and drags his friend towards the school with a cocky grin as Izuku smiles nervously.
Yoake no kehai de michita.
The scene changes to the inside of the 1-A classroom, giving a quick look at all of the students and ending with Yuga, who winks and emits sparkles from his eyes.
Machi wa koe wo, hisometeiru.
The scene changes again to showcase the staff of U.A standing by the entrance of the school. All Might is smiling widely front and center with Principal Nezu on his shoulder, flexing his arms. Present Mic is to his right beside Cementoss, Thirteen, and Recovery Girl. To All Might's left, Eraser Head is being teased by Midnight and looks exasperated, whilst past them stand Ectoplasm and Snipe. The scene ends with chibi versions of Mirio, Nejire, and Tamaki running across the screen.
Yureteiru boku wa,
There's a quick shot of Izuku as a child, curled up on the ground of a classroom and crying as he stares at Katsuki's back. Katsuki has his arms stretched out as if to defend Izuku and is yelling at someone.
sonzai igi wo,
The shot changes to Izuku crying on the ground in front of All Might as a middle schooler where he decided to accept One for All. All Might is smiling in his true form and offers him a hand.
kurayami de sagashiteiru…
The scene changes for a second to Izuku in his first hero costume, looking down uncertainly. A second later, the scene shifts to Eri staring up at him in her dirty white dress, and she reaches up for him with a pleading expression. The third scene is both of them standing in front of each other, and Izuku reaches down to take her hand.
Saenai boku to boku wo kakomu sekai de.
An explosion and smoke cover the screen for an instant, then clears to see Katsuki lunging at Eri's kidnapper with a scowl on his face. The villain hurls a fireball at him, only for Izuku to intercept it with his green flames while Katsuki delivers a vicious blow at the villain's face.
Egaite mo tsukande mo mada tookute.
The next scene is All Might diving in from the sky, smashing the ground and sending dozens of shady figures flying away. He stands up and grins, arm raised in victory.
Nani wo sutereba, soko ni tadoritsukeru.
The camera reels back to show Izuku and Katsuki watching All Might's victory on TV, with both of them looking excited. The scene shifts to show All Might on a different television in a dark bar with Tomura's back to the camera, and you can see the barest hint of him smiling darkly at the end of the shot.
Nando mo nando mo sakende mite mo.
Kurogiri appears the next instant, creating a huge black hole from which numerous villains rush out of. At the back emerges Tomura and Noumu.
Boku wa boku de shikanai kara.
The scene shifts to several of the 1-A students facing off against some of the villains, unleashing their Quirks in quick bursts.
Yume de arou to,
The next scene is Shoto firing off a massive, glacial blast at Tomura, who disintegrates it all with a gleeful smile.
genjitsu,
Katsuki lunges at Kurogiri, roaring at him and barraging the villain with explosives while Kurogiri darts around to avoid the attacks.
darou to!
Finally, there's a quick shot of Eri crying for help, and then Izuku takes up the whole screen, fully cloaked in All Flare with his teeth bared in a vicious snarl.
Kitto koete yukeru.
Noumu swings a fist at him, and Izuku strikes back, his form shifting to All Might's and back for a split second before the attacks collide and send out a shockwave.
Korondatte ii…
Eri's face is shown on the left side of the screen, eyes squeezed shut and crying. Looming behind her is a shadow of Chisaki with his signature plague mask.
Naitatte ii…
A young Izuku is seen on the right side of the screen in an identical shot, with Heat Viper's dark figure visible behind him.
Itsuka sono subete ga hana ni naru kara.
The final scene is of Eri looking at a new drawing of Class 1-A, all in their hero costumes with All Might posing at the front. On either side of him stand Izuku and Katsuki, and she smiles happily.
A/N: Alright, so this is something I've wanted to do for a while that is purely self-indulgent fun, but here's the openings for Viridescent, so if this kind of thing is your cup of tea, knock yourself out! I'm sorry if I monkeyed the grammar in the Japanese bits, I'm not fluent in the language as much as I wish I was. Anyways, enjoy!
