Summary

The sudden disappearance of Professor Tomoe and Hotaru from their residence sends the Sailor Guardians probing into Mugen Academy, which they rightly suspect is bound up with the Death Busters. Their investigation pushes deeper into the school's secrets as the enemy's operations come into sharper focus.

Desperate over her repeated defeats, Mimete steps forward to face the Guardians directly. Her gamble collapses when she is struck down not by her foes but by Tellu, a fellow member of the Witches 5 who eliminates her.

Key Events

The episode brings Mimete's downfall, closing out her run as an antagonist through betrayal from within her own ranks. It also debuts Tellu, whose arrival signals the next phase of the Witches 5 threat, along with the Witches Electric Warp in its only appearance and a voice-only flashback of Germatoid.

In the manga the outcome differs, since Sailor Neptune and Sailor Uranus are the ones who kill Mimete rather than a rival witch.
