The whole event takes place in a place with two powerful kingdoms that were in war each other. In the opening cut , we see the figure of Meiko, supposedly the commander of the other kingdom and it cuts to Miku

which shows Miku remembering the history of the war.

We are then introduced to Rin, an apprentice of Miku, who wanted to give a gift to Miku but was interrupted by a messenger . Throughout the scene, there are cuts towards Meiko

, a fleet of soldiers

and later Luka at

. Luka wearing armor with blue with it seems to show that she was the commander of Miku's kingdom.

Pause the video and tap this> ... as u can see luka is an archer

の子が王様射ったのかね?

In the flashback, we're seen that they have deep hatred for each other. War commences and it was so fatal that it remained as a dark history for both kingdoms. At , through Len's line we know that years has passed since the war Luka and Meiko was involved in. Only now the present rulers, Miku and Kaito, have finally pushed their differences and hatred aside. At

"miku mi ama" es lo único que soy capaz de entender xD

"They sing - melodies desperately praying to all the world" shows that both of them are tired of fighting. The world is ever so desperate since it was the day of their marriage. As you can see Kaito's expression, he's excited this marriage can finally end the feud and the fact he also has feelings for Miku. Through this marriage, he is able to get to know her and become close.

ここからのシーン好き……あとの展開こと考えると平和すぎだな……ヤベェ(語彙力ないが伝われ

While Len was at the forest cooking his meal, he hears something from between the trees and meets Rin. At the same time, the wedding was about to commence between the two rulers by reciting their truce to each other. Len seemingly having an interest in Rin, shows off his powers and they both suck at it.

のレンが、イケメンすぎる

At is that Haku? Meh child

when genshin impact's traveler gets blessed by the pyro archon LOOOLLLL

JJAJAJAJAJA Esos Kagamines!

At the wedding , Miku and Kaito was about to get married until at

, Miku sees a third party aiming their arrow. Miku became scared and was reminded of the war that happened between both kingdoms. While the priest head to get their rings,

At , Miku sees it and reacts, setting the gift to the ground, maybe her reaction was to cancel everything so that whatever was that premonition doesn't happen.

Then at , Kaito sees it, and he seems to be trying to save Miku, or maybe he simply reaches out to her because he's confused. But, he gets shot by an arrow.I don't think they noticed at all that someone was going to kill Kaito, but they panicked because of that premonition.

the arrow is shot into Kaito. Miku was stunned by this assassination and quickly evacuates from the place, for her safety and to ensure Rin was safe while Kaito reaches for help. Meanwhile we can see Len and Rin having a good time with each other and exchanging conversations.

During that time, Rin who is Miku's apprentice tries to gain her attention which Miku somewhat neglect (but she soon regret it) it since her kingdom comes first. And Kaito and Len shares a brotherhood relationship so they have a strong bond. When it is time for the wedding, Rin probably snuck out or she was not invited. And Len didn't know about the wedding so he was shock when Rin mention it in . While the two friends are playing/having fun Miku and Kaito's wedding is about to end but then someone assassinate Kaito. The previous war scene where zoomed in on Luka and Meiko we see Luka is holding a bow. There is a half-half chance that it is Luka's doing. Luka is an archer yeah, but what if someone planned it? Probably the assassin use a bow to kill Kaito as a signal to avert the blame to Blue Oak.

So now I get it.They didn't talk about the marriage between their king and queen but their tradition just different from each other. Len gave Rin a ring for their friendship cuz in his kingdom its just like a gift show their sign of bond they have but in Rin's kingdom its a marriage proposal.Why it take me this long to notice this....

からのは何?どうか心優しい方教ぇてしれ一

But when Len finally arrived , he was confused to see all the commotion around the palace and grabs Meiko's hand, only for her too look back at him with anger and sadness. As Len realizes what happened, he's reminded the time he became careless of his own powers while training that Kaito rushed in to cover him and it ended up injuring Kaito's face

I'm sure It's Luka since she was the "Red" figure in the war holding the bow and I can make up a theory where when she was holding Len at around she was convincing him that the one who killed Kaito was Miku's person but she also seemed genuinely angry so idk

. Again, Len blamed himself for his carelessness and selfishness that Kaito died had he not gone to the wedding with him. Filled with sadness and especially anger, his powers awaken and goes to Miku as he blames her for Kaito's assassination at the wedding.

Len: Kaito-niisama, doushite?

it's nice to make it a sad amv

A Sasuke and Itachi reference? T_T

Kaito is like "Sorry Sasuke, maybe later" and Len is like "Why do you always poke my forehead, Itachi?"

とか完全にそれ

が特に好きです。

OH len looks like link :O

big applause for the illustrator, that pure rage is perfection!!!

At , Miku hugs Rins for the final time as she knows a tragedy would happen. As she looks out the window, she sees Len raging towards her and transfers some of her powers to Rin

and quickly evacuates Rin out from the castle while simultaneously pointing her as the next ruler of the kingdom. At

ミク姉かっこいい(´;ω;`)

Oh no Lens burning down disney land

GOSH DANGIT MY TRIP TO DISNEYLAND IS FOILED

, it looked as if she was trying to explain to Len what had happened and it was too late. Blinded by rage, Len only wanted to kill her as revenge and he did. From afar, Rin saw Miku's light slowly falling to the ground and inevitably also awakens her powers.

Miku's blue light seemingly slowing down and in the next scene

At the end, the image appears again at . The premonition in question would be Len, who simply turns evil.His outfit might somehow hinted at it thorough the song, especially the blade. His eyes too resemble him a lot when he turns absolutely angry.
