August 2007. Gojo starts to handle missions on his own, causing Geto to, as well. One day a certain individual appears before Geto. What's the conclusion that led to Gojo becoming the strongest jujutsu sorcerer, and Geto becoming the most evil curse user?
You would be forcing them to 
evolve using fear and danger,
،سنرغمهم على التطور باستعمال الخوف والخطر
Mittels Angst und Gefahr
würde man eine Evolution erzwingen,
Es decir, sería estimular la evolución.
Lo importante es fomentar la evolución.
La peur du danger les forcerait
In pratica, forzare un'evoluzione 
usando la paura e l'imminente pericolo,
Estaríamos os forçando a evoluir,
По сути, естественный отбор!
