Shino Sasaki/Relationships

Akari Mamiya
Akari is Shino's first friend, who has a very unhealthy obsession for her from keeping locks of her hair, taking pictures of her changing or in a swimsuit, and having an entire shrine erected for her. This has caused her to resort to violence to force Akari to break off her amica contract with Aria. However, despite being obsessed, Shino is fiercely loyal to Akari and would gladly fight for Akari's sake including throwing herself in harms way without a second thought.

Shirayuki Hotogi
As her Amica, Shino is very respectful towards Shirayuki. She also greatly admires Shirayuki not only for her sword skills and impressive status as school but also her mutual hatred for Aria and knowledge of spying on people (particularly people they love). With that being said, Shino diligently studies under Shirayuki and has even borrowed her equipment to spy on Akari. She refers to Shirayuki with the honorific "Onee-sama."

Aria H. Kanzaki
Much like Shirayuki, Shino hates Aria because as Aria's amica Akari is required to work together often or even stay overnight thus limiting the time she can spend with her. Though not as direct nor willing to assault her as Shirayuki is, she can often be found slumped over in depression at the mere mention of Aria's name or glaring at her when she shows up.

Urara Takachiho
Initially, Shino despises Urara due to the fact she constantly talks down Akari. Once Urara is beaten by Akari and she becomes obsessed with her, they become rivals for Akari's attention. Most of the time, they operate individually to win Akari - often times bumping heads should they run into each other - however they have been shown to set aside their competitiveness for the sake of Akari. As the series progressed they learned to become more accepting of each other as shown when they plotted together for the pool trip. After Akari became Aria's full time Amica, their friendship has grown to a point where they'd willingly hangout with each other to discuss what to do next with winning Akari from Aria.

It should be noted that they are foils of each other. Shino has red eyes, black hair, and is very humble about her wealth and easily flustered over Akari where as Urara has blue eyes, blonde hair, and boasts her wealth and is aggressive when it comes to Akari.

Nonoka Mamiya
Similar to Akari, she also has a crush on Akari's little sister, Nonoka.
