Realization...
Ever since the very first time Rio encountered Alverto's clone, he's always had a question in his mind.
Why did Alverto send his clone to that dungeon during the final exams, and what was his actual purpose for doing so?
Rio was unaware of Alverto's purpose, and he had never once seen the character's name appear in the novel he had read.
Someone as significant as Alverto wasn't mentioned in the novel, which is very strange.
If Alverto truly existed in the original novel's timeline, he should have appeared when Fade was executing Demons during the 'Second Demon Extinction War'.
A genius spear master like Alverto, who can use the power of time element to utmost levels, could not have been an ordinary person who was ignored at random.
Up until now, Rio had no idea what was causing this strange change in the timeline.
