Grey (> Hagika aka Grey)

Hagika's classmates described them as a shy and introverted person who always kept to themselves, they didn't expect them to be an idol after they graduated. Hijiri and Percival both thought that she was their manager / producer rather than the leader of Symphony because they were very formal when they met. But after living together, they know that they are nicer than they expected.

Hagika is often seen in the corner or not talking much and it wasn't because they have too many members. Hagika can be often seen working but the members also have to drag them out to relax sometimes. They take care of the group and believe to be responsible for each and every member.

Sometimes, when filming SymParty, they can also be a little loud. They love it when the members goof around. They also often play games with the others. They don't usually cry but whenever the other members were sad, they would also be sad. While many think of Hagika as a logical person, when it comes to their members they become emotional.

Hagika normally doesn't pick a single member but on rare occassions, they would pick Kelly or Percival as their favourite member as they often spend the most time together. Hagika calls them the 2 most extra members and being near them is fun and energizing. They often gather to produce music as well.

They went to Nijioka high school, before they graduated, they were in the idol club that was applied for by them, during those days, they had practiced dancing, singing and acting, they had made multiple appearances in music videos with Kelly who had joined as a dancer just a few weeks after the club was made. During this time they also taught themselves producing and writing music, only when they trained with Mitsugi Studio did they actually learnt how to produce their own high quality music.

Before the finale of the idol cup, their team was falling apart, Kelly had injured herself and the rest had split up because of personal reasons, Madoka had filled in their group last minute and despit being injured, Kelly had performed despite of it. They had won the cup by a small margin from long time winner Mazeru. Guide the Light was what they performed.

HiMit had always wanted to create Symphony with Grey, ever since they started posting music on their channel, she believed that they had great potential to be a great writer, Grey did not expect to be an idol, rather they thought they would be just be a producer but Kelly was most definitely going to be a dancer. They didn't think of themselves as beautiful enough to be idols but after their debut, they have become much more confident.

Grey had also been an evaluator and praised Teruko a lot during his trainee days, they had always felt awkward evaluating trainees that are some much more experienced than them but HiMit had encouraged them a lot, a lot of the members had said that their role model was Grey and do respect them a lot as a leader and often played with them as well. The fake youngest Percival did often let Grey take the lead despite him being the eldest (although in Japan, hierarchy isn't as strict as in korean), Grey had also often praised Percival for his experience and often go to him whenever they needed help.

Although their relationship with their members seem like a long time to get used to, they were already close after their debut. Grey is of course the one that gives all the speeches, very much well known for only crying behind the scenes because they needed to be strong to deliver the speech properly, the members often teased them for being a crybaby off camera, Grey also admits that they cry easily when watching movies. Whenever they were asked who is the member they are closest to, they always make sure to mention everyone despite everyone thinking otherwise but they are touched that they were amendment on having no favourites.
