Also I think the lyrics at are actually counting 1-8, but using the traditional Japanese counting system :0

the comments mostly focus on ~ 8 (hi, fu, mi, yo, i, mu, na, ya) and in japanese, 8 is read as hachi. i think this doesnt need any further explanation.“ne, sensei” im not sure on this, this might be wrong but i read somewhere that syudou used to call yonezu “sensei”.the song proceeds to call what was claimed in suna no wakusei nonsense. the connection to suna no wakusei can be seen from the background in this scene, as well as the font for a split second. the lyrics also are similar to those of suna no wakusei in some parts. then, the song says theyll show “you” (presumably yonezu) something, sorry i couldnt read the lyrics in this part. but i can assume that they said theyll show you success. presumably, success of vocaloids.now, the relation to the gambling theme... what syudou is doing here is pretty much gambling. they dont know if vocaloids will ever really be something big, like the old vocaloid days. but, theyre going on a bet that it will.yeah i think thats it. ill add on if i find anything new.
