Why did you change your VGR identity? (Ver. 2)

Also, uhm, oops. Looks like I've fallen into the near-decade old trend of internet-losers-who-use-anime-girl-avatars.
Oh. Well. :/

Onichan Machine Gun.

マシーンガン。

for those who are too square to play rhythm games, the joke is

basically the song Miracle 5ympho X from beatmania IIDX 21 [SPADA]. An anime girl with pigtails pops up in the video and shouts "ONII-CHAN!"; halfway through the video it cuts to a feet-up scaling shot of her while loading a machine gun. A stock voice announces "Machine Gun", and then, well

she shoots the gun.
On harder difficulties, there's a flurry of notes you need to play (literally the screen's covered in them it's really fucking stupid) to simulate each shot of the machine gun, with a pause in-between each reload.
