But there's also 
a contradictory information presented by the text to the right of the figure.
It states that two years had passed since their last confrontation (Ranma and 
this mysterious individual)

Just an observation on things, and this also kinda
highlights the power that repetition has on the
minds...

Nothing in that text says that the text is adressed to
Ranma, but it's kinda natural to assume it is adressed
to Ranma, right? I mean, all letters of challange
to to Ranma, that's the way things work, right?

Usually.

Now, keep in mind Mike loves to throw curveballs.
