Nakaimo: My Little Sister is Among Them!

Nakaimo: My Little Sister is Among Them!, also known as Kono Naka ni Hitori, Imouto ga Iru!, is a Japanese anime series that aired in 2012. Adapted from Hajime Taguchi's light novel series, the anime enthralls viewers with its unique blend of mystery, romance, and comedic harem-style storytelling.

The storyline revolves around the central character, Shougo Mikadono, a high school student who stands to inherit his deceased father's enormous business empire. The only condition tied to his inheritance is a strange one – he must attend a specific high school and find a suitable wife from amongst the students. Besides this peculiar twist, Shougo also learns he has a younger sister whom he has never met, and she is reportedly attending the same school. Thus begins an intriguing journey of identifying who his sister is to avoid the social taboo of accidentally courting her and simultaneously win the heart of a potential life partner.

The anime promises an unusual set of circumstances that underline the concept of 'forbidden love' and the eccentricities often found in dysfunctional families. It presents Shougo as a good-natured, albeit slightly naive individual who is suddenly tossed into a web of familial mysteries and love entanglements that could potentially threaten his rightful inheritance. The watchword for Shougo is caution due to the precarious nature of his situation. His journey showcases the coming-of-age trials he faces as he navigates through waves of comedy, romance, and light-hearted ecchi subtexts.

Adding an extra layer of spice to the storyline is an anonymous caller who claims to be Shougo's unknown sister but refuses to reveal her identity, leaving Shougo and the audience alike in suspense. With a melange of potential love interests and suspects, the story takes often unpredictable twists and turns as Shougo tries to puzzle out his sister's identity.

The design and animation, from Studio Gokumi, are visually satisfying, offering a palate of vibrant and aesthetically pleasing colors that captures the mood of the scenes perfectly.

The show's cast comprises a set of diverse female characters with distinct personalities and intriguing backgrounds, ranging from an overly ambitious class president, a kindhearted girl with an aura of mystery to a cheerful fashionista. While the central plot of the anime revolves around the relationship between Shougo and the girls he encounters, the narrative also does a good job of delving into the backstories, the hopes, and dreams of these characters. Their multifaceted personalities make it challenging to predict who could potentially be Shougo's sister and who might be the future Mrs. Mikadono.

On the sound and music front, Nakaimo does not disappoint. The background scores are lively, matching the cheerful ambiance of the series, and are often evocative, setting the mood for the various plot turns.

It makes an engaging watch for those who love slice-of-life storylines spiked with humor, romance, and an underlying conundrum to keep viewers on their toes.
