Chou-sensei continues to pursue Shuuyu and Sonshin throughout the school.  Sonshin lacks the spiritual power needed to fully use Shuuyu's abilities, so he has no choice but to flee.  The situation grows even more dire when the two of them are trapped on the roof, and Gien destroys the fire escapes, leaving them nowhere to run...
If I miss, I won't even 
have the strength to run.
وإن لم أصب هدفي فلن أقوى على الركض
Wenn der fehlschlägt,
kann ich nicht mal mehr fliehen.
Si fallo, no tendré fuerzas
siquiera para huir.
Si fallo, no tendré
fuerzas ni para huir.
Et je serais incapable de m’enfuir.
Se dovessi fallire,
non avrei più forza per scappare.
Se eu errar, não terei energia sequer para fugir.
