Genshirou Saji is a third-year high school student at Kuoh Academy in Class 3-C, being the Academy's Student Council Vice-President and is Sona Sitri's Pawn. He is also in love with her. He is a friend and a rival of Issei Hyoudou.
Saji is a young man with short blond hair and grey eyes. He wears the Kuoh Academy boys' school uniform, albeit without the blazer and his sleeves are rolled up. His height is [168 cm] and body weight is [61 kg].
Saji's initial impression was someone who appeared arrogant and egotistic, as shown when he looked down on Issei and bragged about himself while unaware of Issei's capabilities. Saji has an overall personality similar to Issei's and is his parallel in the Student Council. He looks at Sona with the same lustful eyes which Issei looks at Rias with and he cares deeply for his comrades. Saji is also very loyal to Sona, going as far as to say that Sona's dream is his dream and tries his best to help her fulfill her dream of building a Rating Game School that is open to everyone, regardless of status.
Not much is known about Saji's past other than at some point before the series, he was reincarnated into a Devil by Sona, and joined the Student Council in the process not long before Issei also became a Devil.
Saji made his first appearance in Volume 3 along with Sona at the Occult Research Club room to meet with the new members of Rias' peerage Issei and Asia, where they introduced themselves and the whole Student Council to also be Devils. Saji initially looked down on Issei due to his bad reputation but was scolded by Sona for underestimating him as he consumed twice as many Pawn pieces and defeated Riser, which Saji was surprised to find out. Saji was then forced by both Issei and Koneko to lend assistance to Irina and Xenovia in their mission to destroy the stolen Excalibur and help Yuuto let go of his past. This attempt was eventually found out by their masters after their battle with Freed and Saji was punished by Sona in the form of 1000 spankings. He and the whole Sitri team later assisted in maintaining the barrier in Kuoh Academy during Kokabiel's attack. At a later date, Issei invited Saji to come karaoke with his classmates but had declined it while crying as Sona had forbade him from interacting with girls.
In Volume 4, He met with Issei and some of the club members when he heard Rias had released her Bishop, with he finds adorable but was crushed to learn Gasper was actually a boy. Those present where then met with Azazel with whom they kept their guard up believing him to be a threat, but instead he offered advice on how to help Gasper improve with the use of Saji's Sacred Gear. He then put this knowledge to use in helping Issei in training Gasper Vladi, using his Absorption Line to reduce the power of Gasper's Sacred Gear.
In Volume 5, Saji met up with Issei and his group at the party during the Young Devils gathering where Sona told everyone her dream to build a Rating Game school for Devils of all rank, which most of the old nobles laugh at, Saji attempted to fend for her but Tsubaki stopped him since there was no need for it as Serafall's angry glance shut them up. It was then set that Sona and Rias teams will engage in a Rating Game, which over the course of the next few weeks both teams will be training. Saji met with Issei again at the party hall, where he told him his dream to become a teacher at Sona's school which he rants on over excitingly so Issei takes him out to the balcony to avoid the gazes, they both proclaimed to each other they'll win for the sake of their goals. Issei then teases Saji how close he's gotten with Rias, he then ponders if he'll ever have the same relation with his master and expressed his anger and jealousy towards Issei for not being as lucky as he is with girls as he sat in fetal position in depress.
During the Rating Game between the Gremory and Sitri teams, Saji teamed up with Ruruko to fight against Issei and Koneko receptively, he used his lines to ensnare and restrain his movements which allowed him to land a few clean hits. Saji continued using various moves to immobilise Issei such as over charging a lamp post to blind him and as he fired blasts at him, Issei noticed that his blast were stronger than usual which Saji revealed that he has been using his Sacred Gear to absorb his own life force to empower his magic attacks at the cost of his shortening his life, showing how far he'll go to win. Ruruko had just lost to Koneko, she then offered to back up Issei but denied it saying it was between the two of them. Saji then restrained Issei to the ground as he pulled all his power into one more attack hoping to finish him, but Issei brings out his Dividing Gear to only take half the damage, Saji is left with his stamina weakened while Issei activated his Balance Breaker. Despite taking so many hits from Issei, Saji stood strongly and continued to fight back regardless of his injuries, showing the same determination Issei had during his fight against Riser Phenex, he kept until he was forced to retire instead. While Saji was defeated by Issei, he played a big part in defeating him when he used his Absorption Line to absorb Issei's blood during their fight, forcing Issei to retire out of blood loss. Despite his best efforts Sanji's team still lost in the end. At the medical facility, Saji was awarded a medal by Sirzechs for his impressive fight against Issei, Saji trembled in disbelief for he had lost his match, Sirzechs explained that despite so he was still able to cause Issei's later defeat which earned him praise from the spectators including the likes of Odin. Sirzechs praised and encouraged Saji to take and to continue improving himself for his dream no matter how long it takes as he patted his head. Saji cried out tears of joy, especially when Sona also congratulated him for his efforts.
In Volume 6, while the whole academy was practising for the Sports Festival, Saji came to talk with Issei which he showed that his hand had bandaged after a jewel appeared on it after the match against him, which Azazel speculates is due to him connecting and taking the blood of Issei, the Red Dragon Emperor and has caused Vritra's consciousness to reawaken. He then left when Sona and Tsubaki strictly called him out for mingling with Issei and neglecting his work to prepare for the festival.
In Volume 7, the entire Sitri group, Azazel, Baraqiel and the Gremory Group gathered at hall within the basement of Hyoudou Residence holding a meeting with Vali Team who came to from an alliance to fight against Loki.

The next day everyone gathered again at the basement to form strategies while their familiars filled in for them at school. Saji was soon captured by Azazel for "special training" at the Grigori’s institute in the Underworld. He reappears for the final battle against Loki, after Azazel placed three more of Vritra's Sacred Gears into Saji, allowing Vritra to regain his consciousness and allowing him to use more of Vritra's abilities. Saji achieved a new state called Vritra Promotion from using all four Sacred Gears in tandem, albeit while almost going completely berserk. With his new found powers, Saji was able to demobilize and negate Hati and Sköll's invulnerability which allowed for their forces to kill the giant wolves.
In Volume 9, Saji, along with the second-year students of Kuoh Academy, goes to Kyoto for a school trip. He was later asked by Azazel to assist the Gremory Team in their fight against the Hero Faction, transforming into his Dragon King form to battle a mind-controlled Yasaka in her giant Nine-Tailed Fox. He was eventually overpowered by Yasaka until the arrival of Sun Wukong and Yu-Long, where Yu-Long came to assist Saji to balance up the odds.

They are, however, cornered by the three of them after Heracles used the children of the Underworld as hostages, that is until to his surprise and everyone present, Issei arrived on the scene revealing to be alive.

However, the other members of the peerage supported him and his request.

After hearing his passionate response, Sona granted his request and adjusted their strategy for Saji to be able to face Issei.

Eventually Saji and his team were defeated after Sona was retired by Xenovia.
In Volume 24, almost the entire Sitri peerage was protecting Kuoh Town while having also been attacked by the mysterious group of unknown pure-blood Devils.
In Volume 25, Saji celebrated at the Hyoudou Residence to cheer for the teams who won the preliminaries and advance to the main stage and serving a drink to Issei, while expressing disappointment for being unable to fight Issei in the main stage of the tournament but Issei comforts him saying there will be another chance.
