Why does episode 9 of Motto To Love-Ru Trouble say its 25 in the beginning?

You're likely referring to the fact that in the beginning of episode 9 of "Motto To Love-Ru Trouble," the episode title card shows "Episode 25." This is due to a difference in numbering between the original Japanese and English releases of the anime.

* Japanese Release: The episode was originally broadcast as part of a continuous season of "To Love-Ru Darkness" (the second season of the series). In this format, it was numbered as episode 25.

* English Release: When the series was licensed for English distribution, it was divided into two separate seasons: "To Love-Ru" and "To Love-Ru Darkness." This led to a renumbering of the episodes. Episode 9 of "To Love-Ru Trouble" corresponds to episode 25 of the original Japanese broadcast.

Essentially, the title card reflects the episode's original Japanese numbering, while the English release numbering starts fresh for each season.
