"My Friend's Little Sister Has It In for Me!" Anime Episode 10 Preview: Akiteru's Night Raid Apology Mission!

The anime "My Friend's Little Sister Has It In for Me!" is approaching a dramatic climax! The official website has just released the plot summary and preview screenshots for Episode 10, "I'm the Only One Apologizing to My Friend's Little Sister."

Adapted from the popular GA Bunko light novel series, this show has captivated the anime community since its premiere in October 2025, largely thanks to Kohinata Iroha's "annoying yet adorable" charm. In the upcoming Episode 10, the protagonist Ooboshi Akiteru is finally taking action! Not only must he face Iroha's cold shoulder, but he will also launch a "nighttime raid." What exactly is the "most efficient method" Akiteru speaks of? Below is a deep dive into this week's key plot points.

Episode 10 Plot Summary: Akiteru and Ozuma's Joint Night Raid

According to the latest official information, Episode 10 will focus on Akiteru's attempts to mend his relationship with Iroha.

Striking at the Heart: The Target is the Kohinata Household

Ooboshi Akiteru receives powerful assistance from his best friend and Iroha's older brother—Kohinata Ozuma. Under Ozuma's cover, Akiteru successfully "infiltrates" the Kohinata house at night. This dynamic duo from the "Fifth Floor Alliance" teams up once more, but this time, it's not for game development—it's to handle an emotional crisis.

A Closed Door and Akiteru's Countermeasure

Akiteru has only one goal for this visit: to reconcile with Iroha.

However, things don't go smoothly. No matter how much Akiteru calls out from outside her door, a deeply hurt or sulking Iroha steadfastly refuses to leave her room. Faced with this stalemate, the ever-"efficient" Akiteru decides to employ what he believes is the most efficient method.

Making Her "Annoying" Again

The official synopsis leaves an intriguing hint: "To make his friend's little sister 'annoying/clingy' once more, Akiteru's battle begins now!"

This line suggests that Iroha might currently be in an unusually quiet or distant state. For Akiteru, the Iroha who's always clinging to him is the "normal" one. To bring back that annoying underclassman, Akiteru will stop at nothing.
