Titre original : The Strongest Girl in Tenbi
Haruko is annoyed with Takeru: his pratfalls are just too convenient, so he can make his own lunch from now on. Meanwhile, someone is attacking students on the school grounds. Takeru and fellow kenkeibuin Uruchi Minaya are assigned to investigate, but are caught in the spider's web. Haruko comes to their rescue, proving once again that she is Tenbi's strongest.
