Kei Ogata (緒方 圭 Ogata Kei) is the protagonist of PureMail.
Kei is the son of Mrs. Ogata and Tomaru Sawagoe. Early in his childhood, his mother left Tomaru, leaving Kei vulnerable to horrific abuse at the hands of his father. Eventually, social services took Kei away from Tomaru and placed him with his mother, who had remarried to Mr. Ogata and had had another child with him.
Kei is a deeply troubled young man with deep physical and emotional scars due to the abuse he endured at the hands of Tomaru, which included physical beatings and forcing Kei to watch him have sex. Viewing his father as a beast whose genes he carried, Kei constantly struggled between giving in to similar impulses and trying to remain a decent human being despite his childhood trauma.
From PureMail After and the Days series, it can be canonically inferred that Kei lost that struggle and continued his father's wicked ways.
Kei is experienced with computers and prefers using chatrooms rather than conversing in person.
Kei is Yumi's sex slave. He is forced to have anal sex with her every now and then because Yumi has evidence that Kei hacked into the school system before. Yumi threatens Kei that she would report his hacking activity to the school's discipline community if he refuses to do whatever she asks of him. Yumi frees Kei when she finds out that he has a crush on Midori.
Miki is Midori's best friend, and she also has a crush on Kei. Her feelings for him remain unchanged even when she realizes that Kei is interested in Midori rather than her.
Miki attempts to pursue Kei by tricking him on going to the summer festival with her, saying that Midori would come too. When Kei finds out the truth, he takes Miki to a nearby river where it's dark and violently rapes her when the fireworks start.
The following day, Miki avoids Kei at school. Kei regrets what he had done to her, so he arranges to meet her at a park after school. Kei apologizes to Miki at the park; Miki tells Kei that she knows who he is really in love with and vows that she would not report being raped by Kei as long as Kei promises that he would take good care of Midori.
Ai is Kei's younger half-sister. He displays some annoyance to her especially when she asks Kei whether or not she looks good in a certain piece of clothing; deep down, however, Kei cares about Ai like any older brother would.
Midori has always been Kei's love interest; he has been in love with Midori ever since Kei met her as Eve on a private internet chat. They talk very openly on the chat, including personal stuff.
Kei falls even deeper for Midori when he finds out that she is his classmate at school. This love is not one-sided, as Midori is also in love with Kei as AW; and at a later point in the story, falls in love with his real self at school too.
Ever since learning of Midori's true identity, he often sexually fantasizes about Midori being naked. Kei is shy in expressing his feelings to Midori so he unintentionally puts up a cold front towards Midori, causing her to think that Kei dislikes her.
Despite the initial misunderstandings, Kei eventually invites Midori over to his house for a study session, and finally confesses his feelings to Midori. Midori reciprocates his feelings and they kiss. The couple proceeds to have sex on Kei's bed. Unfortunately, Midori brings a sad piece of news to Kei -- she has moved to another city due to her father's work but she promises to keep in contact with Kei via mail and that she would also be with him again when she grows older.
Although Midori never found out about AW's true identity, it is shown that Kei placed a higher position in Midori's heart than AW, evidenced when Kei asks Midori what she did last night on the chat, with Midori replying that she merely had a study session at Kei's house without mentioning that she also had sex with Kei.
It is also mentioned that he'd fathered Korin Sekihata via Rin Sekihata. Several years later, when Rin and Korin reunited with him, Kei molested their daughter, causing Rin to end their relationship.
