A lone woman appears when Kathleen is in danger. Is she an ally or an enemy?! Will they be able to escape from the desperate situation within the tunnel? Sensui's past is finally revealed, along with his history with his Master and the origin of his dual wielding style...
Maybe it's because it's always 
been just the two of us.
ربّما لأننا نعيش نحن الاثنتان لوحدنا معاً دوماً
Vielleicht liegt es daran,
dass wir beide immer alleine waren.
Debe ser porque siempre
estuvimos las dos solas.
Debe de ser porque siempre
estuvimos las dos solas.
Ça fait si longtemps
qu’on vit ensemble.
Forse è perché siamo sempre state noi due da sole.
Acho que é porque fomos
sempre só nós duas.
Наверное, всё потому,
что мы всегда были вместе.
