So we all know Gojo took care of Megumi right? So he must be familiar with Megumi sister Tsumiki too? So when Tsumiki was cursed why didn't Gojo do anything? Like seriously Gojo pretty much raised Megumi definitely he knew Tsumiki then he must have also knew about Tsumiki being cursed but he did nothing? Or it's like gege made Tsumiki is just an cannon fodder for Megumi character development?
