Notes:

Following up on the previous pic of SeX by herself.

Series S-tan is the little sister of Series X-tan. Compared to her big sister, "SeS" is more petite, less buxom, and with a cheerier color scheme and disposition--though she maintains her sister's wide hips, cybernetic motif (most notably their glowing electronic eyes), and sweet personality. Both are far more powerful than most other console-tans, with only PS5-tan placing between SeS and SeX, while SeX herself is currently only beat out by PC.

Where SeX is a shy, gentle mute despite her massive power and tall, intimidating appearance, SeS is a curious and affectionate little oddball whose silence comes from her lack of mouth. In fact, this along with her porcelain-white skin makes SeS appear outright synthetic compared to the cyborg-like SeX, though much like SeX, SeS is never seen without her bodysuit, which trades her big sister's disc-slot stripe down the right leg for a round mesh cutout on her belly (and feet) based on the fan grille. She also isn't particularly bright, and unlike SeX's trouble socializing due to her timidness and her ominous looks scaring others, SeS is more likely to cause awkward situations in her eager attempts to play, exhausting the others and weirding them out.
