Appearance[edit | edit source]
Personality[edit | edit source]
A cheerful labor (part-time job) boy, Kakeru is lively, works with all his might with little complaint, is rarely discouraged, and does not like to lose. Despite his unlucky constitution, he starts his day in high-spirits and top-form. He is the type who will only continue to grow as time passes.
With this, Kakeru carries a strong sense of pride and believes in self-reliance, as shown by how he chose to work part-time to support himself instead of relying on his parents' allowance since it was his choice to move out of his home. 
Kakeru also shows great love and appreciation for food, in part due to him living on his own prior to moving into the dorms, as well as being in a stage of rapid growth and metabolism. However, he isn't selfish and is more than willing to share with others, and is also aware of how he should watch his calorie intake
Kakeru does feel uncomfortable when it comes to his height sometimes, especially due to him now being the shortest among the two groups. At some times, he feels as if his height makes him seem like a person isn't very dependable, and, while he doesn't dislike it, he gets treated like a child.
History[edit | edit source]
Kakeru is the only child of Shiwasu Ayumu and Ayumu's unnamed wife, and it is heavily implied that he comes from an affluent family since his father has the financial power to do rather grand things such as taking a helicopter to his entrance ceremony, turning the apartment he had been staying in into a castle, and buying almost anything and everything Kakeru looked at.
Before debuting, he ran away from home due to mishaps involving his parents, particularly his father - one of them being his father surprising him for Christmas by blowing his room up. He had been living on his own and had been working several part-time jobs to support himself.

Height: 163 cm
Kakeru, in his second year in junior high school, had been living on his own and working part-time at various jobs, including that one at a bakery, during the Christmas of 2012. He arrives at his apartment one day only to find that his father, as a Christmas gift to him, had the apartment he had been staying at had been remodeled into a castle. Deciding to no longer stay at the apartment, Kakeru heads to the park, where he has his encounter with Kuroda and Tsukino Mikoto, the President of Tsukino Talent Production. After laying down the "terms" of the work he was being offered, Kakeru was (almost forcefully) scouted.
After being scouted, he, together with Kisaragi Koi, Mutsuki Hajime, Yayoi Haru, Uduki Arata, Satsuki Aoi, move into the Tsukino Dorms and the six subsequently form the idol unit Six Gravity. Not long after, Six Gravity's sibling-slash-rival unit Procellarum was formed, and the two units proceed with their idol work individually and side-by-side. Given the increasing work of being an idol and a student, Kakeru does not involve himself with other part-time work anymore.

Relationships[edit | edit source]
When they first met at their missionary private junior high during their first year, he and Koi became instant, close friends, to the point that they often have fights. He and Kakeru are often paired up together when it comes to idol work, and both have an energetic type of dynamic and suit each other quite well, and end up being the ones who liven up the dormitory quite often.
Additionally, since Koi has a generally lucky constitution, he with his good luck and Kakeru with his bad luck even each other out.
Kakeru also maintains a friendly relationship with Koi's family and often exchanges mail with Koi's father.
As with most goddess candidates, Kakeru sometimes appends "-chan" when referring to Kurisu, implying a sense of familiarity between them. When given a chance to interact, the two get along quite well, with Kakeru acting as a sort of older-brother figure to Kurisu, such as scolding her when she spoke in a rather crude way.
Kakeru seems to see Hajime as a king-slash-father-figure of sorts among those in the dormitory, almost to the point of calling him "Father" in his character profile. Kakeru has no reservations towards Hajime, and quickly approaches Hajime with hospitality and respect. He also tends to redirect Koi to Hajime whenever the former has problems with his schoolwork. Hajime harbors a soft spot towards those younger than him, Kakeru included. One manifestation of this is allowing him and Koi to keep Croquette at the dormitory after the two asked him for permission. For some reason, Kakeru has not been subjected to Hajime's Iron Claw, unlike Koi.
Haru sees the Kakeru and the younger ones as those who liven up the dormitory and treats them as an older brother as well as serves as some sort of mother-figure. Also, Haru sees Kakeru and Koi as most suited to being the hosts of the Tsukiuta. Radio and places a lot of trust upon them, although sometimes questions the jobs given to them, since they seem different from what idols usually do.
Arata sees Kakeru as a younger brother of sorts but tends to treat Kakeru better than Koi. Kakeru also carries no reservation towards Arata and gets along with him better than Koi.
Aoi sees Kakeru as a cute younger brother but acknowledges Kakeru's skill as the one of Tsukiuta. Radio's leading personalities. On the other hand, Kakeru recognizes Aoi's status as a good-looking person on a level above his. But does nevertheless treat Aoi no differently than everyone else, seeing him as an older brother and a reliable co-worker, as well the one who cleans up after himself best.
Kakeru's parents are currently overseas, but are very supportive of Kakeru being an idol, particularly his father, Ayumu. However, Kakeru clashes often with his father, due to his father's tendency to try and spoil him with eccentric ideas, such as blowing up his room for Christmas, turning his apartment into a castle, or taking a helicopter to his junior high school entrance ceremony. Since Kakeru is an only child. His father heavily spoils him, and always wants to be acknowledged by his son, such as when he called out for Kakeru when he was seen on TV during the World Cup. Kakeru is closer to his mother, who Kakeru describes as fun-loving and always smiling, and with minimal complaint goes along with her husband's ideas. The two also have no major problem with Kakeru living away from them, and continued to support him financially.
Kakeru worried about Rui when Rui stopped to take a rest in an errand for Kai. He asked if Rui feels fine. Later on, when they have lived in the same dorm, their relationship develops pretty well.
