Author be like "You thought he was on time? Ha, gotcha, everything already happened a while ago!"
wow, skip scene. suddenly, guardian saint woke up and his little sister was gone
they never claimed that they were smart. only evil and loves to torture everyone who ain't them.So they've kept their "Guardian Saint" on ice for who knows how long, and they expect him to just follow orders without any resistance?
Immediate thought that came to my head, why doesn't the sister just try to kill them again.
