And yes, all of the music heard is in the description. The track played during the Nyo segment is "Tengu-Mai," a track from the DOA2 OST (played during Ein's vision of Bankotsubo). I'm not sure if it originated from another game, if it's a common tempo associated with tengu or if it began with DOA. Either way, the link Rev posted sounds pretty good.
4:16 = Miss Tengu: "lol Tina, you should know better..." 5:04 = Leon: "Welp... life bar is about to magically disappear. GG's." 5:11 = Leon: "Aaah shit... spoke too soon." 5:23: "lol Doesn't matter. See ya." 5:32 = Ryu: "... I don't care." 5:46: Ryu: "Zero fucks given." 6:20: Ryu: "Ein, come on now. Give it a rest."
1:40 = Ryu "Naw. I'M RUNNIN' DIS BITCH!" 2:06 = Momiji: "My ass is invincible!" Ryu: "... lol And?"
3:05 = Ryu: "Enough! A true ninja does not whiff as much as you do!" 3:13: Ayane: "Don't me lau - AAAACK!!" Ryu: "Uh huh. Sit down." 3:26 = Ryu: "You're not safe either. Get back on the bench."
3:37 = Ryu: "What are you doing?" 3:42: Ryu: "... That's twice..." 3:46: Ryu: "... lol Forget it. It's Troll O' Clock anyway."
@samuraihachi: Thanks. I knew it had to do with Mortal Kombat's Scorpion, but since I'm not all too familiar with the games, I thought the song was fan-made and not official.
Izunas are destined to drop in the end. I still have much left to do.
