The Apocalypse has locked thirty thousand players inside the game, and no one knows what to do.  The larger guilds are taking over Akihabara, and outside the city violent groups are Party Killing other players.  A young female member of Marielle's "Crescent Moon Alliance" is trapped in Susukino, far to the north, and needs their help.  Shiroe feels somewhat embarrassed, but makes a decision.
And during that time, you'd have 
to fight monsters, of course.
Auf dem Weg dorthin sollte man auch
davon ausgehen, auf Monster zu treffen.
Y durante ese tiempo, hay 
que pelear contra monstruos.
Sans oublier
les attaques de monstres.
E durante il viaggio
 devi combattere i mostri, ovviamente.
E, durante esse tempo, você terá que
 lutar contra monstros, é claro.
Полагаю, что на пути 
точно встретятся монстры.
