You can find all these songs I mention on YT. Initiation feat. Hatsune Miku Initiation feat hatsune miku siinkora remix Reincarnation Ascensation (?) - Typing in the japanese title can give you more covers of it.
The best cover was made by Luka Megurine, and I also recommend Rin power cover too. Glide- Lily WAVE- Lilly and there's tons of PV - Cover by Gumi,Tei Sukone, and 96neko. Circus Monster- Haku Yowane (Best cover of circus monster and it's not a pitch down song.
It's haku's real voice) Cyber Thunder Cider- VY1V3 Mizki Hurting for a very painful pain VY1 VY2(suceeding version by VY2V3) Kuso Mesorogiwi - Rin with the thumbnail that has rin with longer hair and holding a pink phone Kuso Mesorogiwi Alty remix- Len Kagamine Just be friends migikata no chou Vocalmash uploaded by ZephyriaGenevive Migikata no chou chorus uploaded by grbo123.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
