Aaaa was a fat man who wore glasses and was not good-looking. He generally has a cross-weave head band and a black short sleeve underneath his jacket.
Aaaa was a net game NEET who welcomed the announcement of Sword Art Online becoming a death game as he could play online games consecutively this way.
He was a lolicon[† 2] type of person, thus he rejected love from older females and fell in love with Silica, who he began to stalk from the time she woke up to the time she went to sleep everyday. He has also warned Kirito repeatedly to take care of Silica, otherwise he would butcher him.
He was introduced as a net game neet. In Sword Art Online, he was a strong player, as he was a member of 75th Floor's clearing raid.

In Chapter 2, when Kirito partnered with Silica, Aaaa threatened to butcher Kirito if he did something strange to her.
In Chapter 14, he was seen joining 75th Floor's clearing team by Kirito, but was not found after the boss was cleared, thus Kirito came to the conclusion that he must have died during the battle.
Aaaa was a temporary name that the character had chosen when he initially created his character, planning to make a proper name after he got used to the game's system, but SAO's change to a death game happened before he could do so.
Aaaa is similar to Kirito in such aspects as being a hardcore gamer and being a strong player, but unlike Kirito, he died during the last boss battle.
