yes, it is obvious that whisper gave keita the watch at the very beginning of the yo-kai watch franchise. and inaho got hers in the beginning of yw3. so this may sound like a stupid question at first.
however, in forever friends, ancient enma says something that basically contradicts how they obtained the yo-kai watch.
"until the day humans and yo-kai can truly walk hand in hand, the yo-kai watch is to be sealed away." (not exact words but something like that)
M02 is when humans and yokai truly end their discourse, which is a significant amount of time AFTER keita got his watch. inaho is there too with her model u watch.
if forever friends is canon, how did whisper obtain the watch when its supposed to be sealed away? and how did the model u escape from that seal to be given to inaho?
