List of Theories Updated so Far
Well, Iāve been thinking that many theories have been lost in time as more chapters appear, therefore, in order to make it more comfortable for readers, Iāll give a link along the theory name so in case thereās curiosity, you can check them faster!!
Along this, the list will be updating if new theories come over with time.
