Bald Force EXE resolution



it's an anime.It has four episodes...the ending is quite sad.Here's the plot from wikipedia and crunchyroll:
Any network runs all over the world, and the development of the information network reaches its acme. In this age, there are two developed worlds; “the real world” and “wired”, or the virtual network world.

Baldr Force EXE is a world bigest hacker of the US military,in the mid 1980's Baldr Force, boasting fast action and detailed sprite characters. The game feature a world in not so distant future, where human able to dive in the network, and fight using a humanoid tools called "Simulacrum".

As a hacker of renowned hacking group "Steppenwolf",Toru Soma(or Soma Toru) and his partners earn their living by hacking into servers and selling the information they steal.
As the last hacking before disbanding their group, they hacked into a military server, but soon they find this is a setup by the military to lure terrorists, and they were drawn into battle between two factions. At the end, one of Toru Soma's friend , Yuuma, was killed by an unknown Simulacrum, while most of other group members have been arrested. To investigate and avenge his friend's death, Toru Soma accepted the offer to join the military.

Then as the story progresses, Yuuma is killed by Ayane in Toru's team in the military. She wanted too kill Genha who killed her brother. And so then , she is kept in jail due to her selling miltary secrets. Later, Toru is revealed to be an experimental body of the military( same as the people in Fei Dao, an extremist group who threatens to disrupt the stability of the wired world). He has a little sister, Ren. It was that Toru recovered his memory and went to look for his sister's real body so that he and his sister can be together in the real world. However, ren is dead. Her body is found in the old research lab and has become a skeleton. Ren= Envy ( the network ghost?She comes with a virus and lives in a network world). After ren know she's dead, she somehow become crazy and then the virus and her like merged together and making people in the wired world disappear. Then Toru goes and destroy it.In the end, it is quite a pity that Toru and Ren could not be together.
