The Musical (Original and Revive)

As you may know, a stage musical, "Vampire Knight", had a 5 night run in January 2015 and another 5 night run in July as "Vampire Knight -Revive-" (same script, different main theme songs). There is a DVD recording available with 30 minutes of behind the scenes footage and interviews. There are also two CD singles sung by Akira (Kaname), featuring new art of Kaname drawn by Hino.

Tragically, there is no full soundtrack release, nor can I find the official lyrics or even official titles of the songs. (DOES ANYONE HAVE THESE?)

I am working on transcribing and translating the songs. There are 17 distinct songs of varying length, (19 altogether but 2 have word-for-word reprises). I WOULD LOVE SOME HELP WITH THIS PROJECT. I am very much a novice at Japanese, and having to go entirely by ear is difficult. Even listening to each song multiple times in slow motion has still left me with some lines I am totally confused on.

Even if you're only a novice as well, I'd at least love a second opinion on what I've done so far. Here is an example of what I mean. This is the song #9 that plays from 53:15-55:14. I've arbitrarily named it "Second Bite/ 'It's Alright'". Words in [] are words I couldn't hear clearly or didn't know the best way to translate.

Japanese:

"いいよ。私の血を飲んで。殴りなれるから."
これていい。私に出来る。ただ一つのみだら[なやまち]。
[かわいい楽からた？]、もう止められない。
いいよ。止めてあげるから。約束する。何度でも。
[あまぐ変わるはなぞので、今お前を感じてる。??] > Yuuki and Zero may be singing different words in this line.
誰にも、知られちゃいけない。
許されないをどうしよう?


English:

"It’s ok. Drink my blood. That’s how we’ll beat this!"
It’s alright. You can use me. [It may not be right but it’s the only way.]
[If you make this easy,] I won’t be able to stop.
It’s ok. I’ll stop you, I promise. As many times as it takes!
[As I transform, I think of you??]
No one must know of this.
How can I ever be forgiven?

~ Please help me translate these wonderful songs so more people can enjoy them! Thank you
