Issei Hyoudou
He's a member of the Occult Research Club, and his rank in Rias' peerage is Pawn. His power as a Devil ranks at the bottom in the beginning (which increases as the series progresses, until eventually he becomes the strongest among the young Devils and develops his strength into SS-Class); however, on his left arm, he wields the Sacred Gear, Boosted Gear, making him a dangerous opponent to underestimate. His goal is to one day rise in rank to that of a High-Class Devil so that he can gather his own servants and create his own harem, becoming a "Harem King".
Appearance
While he has worn various outfits throughout the series, his most commonly worn outfit is the Kuoh Academy boys' school uniform, which consists of a blazer (more commonly black, although in other media is shown with a tinge of purple or grey, with white accents) over a white, long-sleeved dress shirt with black highlights with a black ribbon on the collar, matching black pants, and brown dress shoes. However, Issei's uniform differs in the fact that he wears a red T-shirt underneath his open dress shirt and blazer, and wears blue and white sneakers in place of dress shoes.
From the end of Volume 2 to the beginning of Volume 12, Issei's left arm was transformed into that of a Dragon. In order for it to appear human, a ritual would be performed where Rias or Akeno would suck the power of the Dragon out of it, allowing it to appear human for a few days. After gaining a new body in Volume 12 through the combined efforts of Great Red and Ophis, he is now able to freely transform any part of his body into that of a Dragon.
Personality
One of the many personality traits that define Issei is his ongoing perverted nature and his obsession with women's breasts. This has caused him to be instantly labeled as a pervert among the girls of Kuoh Academy and has gained him notoriety for being one of the members of Kuoh Academy's Perverted Trio. Despite his pervertedness, he has attracted the following girls: Rias, Asia, Akeno, Koneko, Xenovia, Irina, and Ravel. This is due to his kindness and unwavering determination of wanting to protect and help those who are important to him despite almost dying by the hands of his opponents. He is, however, oblivious to the feelings of the girls around him (save for Rias), often believing they are simply teasing him. Even with Rias' family telling him to use the same titles for them as Rias (Father, Mother, Brother, etc.) and other mentions of engagement activities, he still remains the same.After his murder by Raynare, Issei had developed a fear of admitting his feelings to the girls, as he thought it would cause them to turn their backs on him. He acknowledged that this would never happen, but it was still an intense fear. However, by Volume 10, that fear had been overcome.

Appearance

styled in a short bob cut and violet eyes. She wears a pair of red
glasses and the Kuoh Academy girls' school uniform.
Personality
Throughout the series, Sona is shown to be a very strict type of
person. Whether it is a matter of the Student Council or the Sitri Clan,
she does not take anything lightly. Sona is very dedicated to her dream
of opening a Rating Game School that is open to all regardless of their
status, even going to a human school to learn of their system. She also
is very protective of her big sister, Serafall Leviathan.Gray Fullbuster
