Absolute Anime

the first episode about i just saw the second one yesterday and i was kinda confused
Are they in a game

yea Rena is shugo's twin sister and they were seperated by parents. Rena won a contest for the both of them and now they resemble the legendary dot hackers. they finally get to see each other after years of seperation but in a game. Shugo tries to protect Rena and he ends up dying but this girl named Aura gave him life and Kite's legendary bracelet. thats basically it.

but how did they get in the game or is it like a rpg

its a virtual reality game that comes with a helmet and u have to download it from the comp so Rena just basically forces Shugo to play.
