Kuga Issei

Kuga Issei (久我 壱星) is an idol under TSUKINO TALENT PRODUCTION. He is a member of the unit QUELL and the older twin of Kuga Ichiru.

Appearance
Issei is a young man of average height, with black hair with long bangs framing his face and dark blue-purple eyes. He is distinguished from his twin, Ichiru, by the fact his bangs are swept to the right and he is typically seen with a more neutral expression.

Personality
"'The glow of the evening's first star in the faraway sky is lonely but beautiful. The half of serenity.' -TSUKINO PARADISE profile"

Issei is quite shy, especially when compared to his twin Ichiru, having been described as soft-spoken and introverted. He can come off as anti-social sometimes due to his shyness, but he does his best to come across as polite to others, especially if Ichiru is being a troublemaker.

Issei is more intellectually oriented, as opposed to Ichiru who is more physically inclined; he's exceptionally smart and has proven to be capable of learning just about anything through observation, and as a result, is extremely observant. Eichi was surprised to learn how inquisitive Issei is, saying that he is always asking questions.

He seems to doubt himself somewhat, as he currently is unsure if he's cut out to be an idol. Additionally, due to his introverted nature, he has great difficulty dealing with crowds, and due to his frail body, they can sometimes make him feel physically ill.

History
Ichiru and Issei come from an orphanage in Hokkaido. As a result of growing up in an orphanage, the twins never went to high school, instead, they worked at a production factory.

Plot
2016 = In late March/early April in 2016, Issei and Ichiru encountered Izumi Shu while he was on a press tour in Sapporo, after learning of their difficult circumstances he offered to take them back to Tokyo with him. He then introduced the twins to the president of TSUKINO PRODUCTIONs who eventually agreed for them to debut as idols.

While leaving the meeting the trio ran into Eichi, an assistant director Shu had befriended while filming one of his TV shows, who was promptly invited out to dinner with them by Shu. Over the course of dinner, Shu proposed that Eichi should become their unit manager causing interesting reactions in the others. Eichi instantly panicked at the suggestion meanwhile the twins were confused about being in a unit; Shu failed to communicate his intentions clearly.

Eventually, Eichi decided to take Shu up on his offer and soon quit his AD job to become QUELL's manager. Thanks to his skills from his previous job combined with his friendly personality Eichi proved to be a competent manager and enjoys fussing over everyone, especially the twins.

One day the twins suggested that Eichi should become an idol too, due to his good looks and impressive dancing skills, rather than be their manager. Eichi once again panics at the suggestion, but Shu agreed that it would be a good idea; leading to the full formation of QUELL.

QUELL
Izumi Shu - Despite having only just met Issei and Ichiru, when Shu first met the twins he was so moved by their unfortunate circumstances that he wanted to bring them back to Tokyo with him, and hopefully give them a better life. The twins later revealed that at first they found Shu to be so kind that they thought it was almost suspicious, but Issei simply found Shu to be a mysterious, but genuine, person.

Since then, Shu has become over-protective of the twins, especially Issei due to his weaker disposition and more introverted personality. Issei and Shu also bond over their mutual love of reading, Shu often recommends books to the twins but Issei is the only one who actually reads them.

Horimiya Eichi - While Eichi hasn't known the twins as long as Shu he quickly came to care for them and upon joining QUELL as their manager he immediately started fussing over them and taking care of them. Like the other members of QUELL, Eichi has a tendency to be over-protective of Issei due to his more introverted nature and frail body. Eichi and the twins spend a lot of bonding time in the kitchen together due to their proficiency with cooking, and usually, they're the three in charge of cooking dinner.

Kuga Ichiru - Despite Issei being the older twin, Ichiru is the one who is overprotective out of the two, just like the rest of QUELL. This is because Ichiru recognises how introverted Issei is, and how much difficulty he has around crowds and new people. Ichiru easily gets mad on Issei's behalf, because he knows Issei won't say anything otherwise, and while growing up he used to get into fights so often as a result that he would carry bandaids with him.

Due to growing up with no other family the twins are extremely close and do pretty much everything together, despite their differences in personalities and interests. To this day, the twins still often fall asleep together in the same bed, often while holding hands; Shu and Eichi find this cute and often take photos of them.

SolidS
Issei has said that he finds SolidS to be kind and down to earth, despite their popularity and experience with being idols. He finds them inspiring.

Takamura Shiki - When discussing who was different from their first impressions within the two SQ units, Issei said he was surprised to learn that Shiki was an interesting/funny person.

Okui Tsubasa - Despite Tsubasa and Ichiru not getting along based on their initial meeting, Issei says he thinks the two actually have a lot of similarities.
