This is it. The culmination of 14+ hours. Thank you very much. I love it. If I have a time machine the first thing I do would be to go back and skull fuck the idea of this song out of whoever who make it, because I'm pretty sure this relay violated the geneva conventions.
Best sound go to Shizurin, who sounded close to the original.
Best animation go to Deron's ponytail. Rena's twintail spin was a strong contender but this thing has a mind of its own, I tell you.
Special mention to Sasaki, who has two unique pose compare to everyone else's (half) spin.

Now that's out of the way, let's talk about the second stray cat stream. Unfortunately it's unarchived so that's 14 hours of glorious content, lost. I'll try my best for a tldw, but the latter part of nijinyanji is loaded with livers that I actually follow, so I was only able to watch her between relay.
- This stream is pretty much the cat hunting for unwilling prey to do her bidding.
- She called two victims to sing for her while she went out to buy a cola, unfortunately I wasn't able to tell who they were.
- Called Gilzaren, made him sing a duet. Called him again when he run away. The man complained it was torture.
- Called Tamaki (the trap). He asked if the stray cat is hated. When invited to sing, ran away successfully.
- Sister Claire called. Even though she was in the project, she was forgiven because she is sister Claire. Sister Claire embarrassed voice when sing live was cute.
- Called Sango. The poor girl screamed her lungs out while the stray cat left to buy dinner.
- Returned when Sango was about to die. Cross the finished line alone. The one cat relay ended in triumph.
Moral of the story, this was the longest stream she has ever done, more than double the second longest in length (5 hours) she did a year back and it was unarchived because management doesn't have the balls. Also never let anyone tell you that salty is not enough motivation to achieve greatness.
There was a sped who took this marathon super seriously and spam that she deserved to be left out of the event because of her normal behavior, and it's "arrogant of her to think management will give her a chance rather than the other livers who works hard everyday and doesn't complain or go against management all the time". Which is of course retarded if you even remember that she was invited to MC for nijisanji end of the year stream with the JK Gumi, which composed of the three undisputed top nijisanji livers and was given an award herself.
In case you haven't noticed, only those with 3D models are invited to nijinyanji.
