Isaku Senagaki

**Isaku Senagaki** (瀬名垣 一咲, *Senagaki Isaku*) is the main protagonist of the manga and upcoming anime series: A Girl & Her Guard Dog.

Ever since her parents had died from a car accident early on in the series, Isaku has been under the care of her grandfather, Tasuke Senagaki.

Because of her reputation as "The granddaughter of a (3rd Generation) Yakuza boss", Isaku wasn't able to make any friends as a result. But in spite of this, she's determined to change that upon enrolling to Otowa High School, with the desire to experience normal high school life at its fullest.

Although Isaku is more than ready to make an official debut as a normal high school student, what she doesn't seem to be aware of... is the fact that her guardian/unrequited crush, Keiya Uto, has blatantly lied about his age - in order to attend the same school as her.

## Appearance

Isaku is a very beautiful teenage girl who stands at average height. She has waist length platinum blonde hair with bangs that frame both sides of her face, a fair complexion, soft purple eyes, and full pink lips.

When in school, she dons the standard uniform for girls, which is a white and navy colored **seifuku**. However, during social outings or at home, she is seen wearing casual but feminine clothes.

## Personality

Isaku is initially known for her serious, but timid disposition. Because she wasn't able to make any friends at all throughout her childhood, due to her family's lineage, she became socially inept as a result. However, this doesn't claim her as "anti-social" by any means.

Even though Isaku is seen as introverted, she's proven determination and independence at the point when she enrolled herself into the school of her choice, as she aspires to have a normal high school life filled with friends, as well as gaining exposure to having a typical love life.

Outside of her reclusive nature, Isaku can be seen as openly vocal in her interactions with Keiya Uto. Though, the interactions between them would usually consist of her scolding him, whether the latter tends to treat her like a child or whenever his overprotectiveness becomes too excessive.

## History

Isaku was 5 years old at the time when she lost her parents in a car accident, prior to the start of the series. Since then, she started to live with her grandfather, Tasuke Senagaki.

At the point of being taken in by her grandfather, who serves as the 3rd Generation Boss of the Senagaki Yakuza Family, a child Isaku meets Keiya Uto for the first time, where he is then assigned as the former's guardian. Albeit with the task of having to protect her.

Initially weary of him at first during their first meeting, Isaku bursts into tears when she cried out for her parents. And because Keiya didn't want to see her cry, he gradually embraces her and states that - even though Isaku's parents are gone, he can be able to compensate for parenting by acting as both "mom and dad", along with promising the young girl that he'd be able to protect her forever. Something that led Isaku to cry even more, albeit out of comfort.

Since meeting Keiya for the first time, this was the moment where Isaku started to fall in love with him.
