After being told by the Game Master to hit on a certain girl, Yotsuya sneaks into the girls' restroom of an unfamiliar high school and saves Tokitate Yuka from being bullied by her classmates. Tokitate turns out to be the fourth party member. When she's summoned into the other world, Tokitate develops a deep admiration for Shindou, whom she sees as much stronger and prettier than herself.... but Shindou also has a past that she can't tell anyone about.
If we end up in some kind of future 
where we fight to defend this city,
إن قادنا الأمر لمستقبل نقاتل فيه
،للدفاع عن هذه المدينة
und wir in einer Zukunft landen, in der wir
kämpfen müssen, um diese Stadt zu beschützen,
Si nos depara un futuro
en el que debamos defender la ciudad…
Si nos depara un futuro
en el que debamos defender la ciudad…
et que notre but est de le combattre
pour protéger cette ville…
Se finiremo in un futuro in cui dovremo combattere
 per difendere questa città,
Se acabarmos em um tipo de futuro onde
vamos lutar pra proteger esta cidade,
Если мы окажемся в будущем, где придётся
сражаться ради защиты города...
