98SE-tan (Japanese: 98SEたん, 98SE-tan), also known as Secchan (せっちゃん). She has a sister called Hacchan, who represents Windows 98 First Edition.
Secchan has an appearance of a middle school girl in a turquoise sailor uniform and a yellow bow, and has short, periwinkle hair that is tied to the side, In the early days, her design was a boxy figure akin to Vulcan from the anime "Zatch Bell", known as "Konjiki no Gash" (金色のガッシュ!!) in Japan. However the current design eventually became official, despite the Vulcan box figure still being used as either a toy, or something she can go inside of to either hide, or control with.
Secchan is also shy, but unlike Hacchan, she is more easily angered. She is a fan of professional wrestling, thanks to Hassan's (male version of Hacchan) experience as a wrestler. She likes to say "Mau mau" (まうまう).
