The vice-president of the Gehenna Renaissance Committee, Karen. While sharing the same passion of making Gehenna great again with her fellow colleagues, she takes on a more laid-back approach, mostly supporting her friends whenever necessary while they do most of the work. That's not to say she's lazy, with her spending her free time protecting Gehenna students outside the district, persuading them to join the club. Despite her more laid-back approach, Karen has her own ways of changing Gehenna for the better. Aside from helping her clubmates whenever she can, she spends time as a vigilante to protect the students of Gehenna outside of the academy district. Although she vouches for a new and orderly Gehenna, a part of her adores the chaotic vibe of it. Perhaps it's a reflection to how violent she can get when in a fight. Karen has purple eyes, a very long, light pink hair adorned with twintails, a pair of cone-shaped hair buns on top and braids which are cutely shaped like bows on each side. A small, singular pink wing can be seen behind her waist. Sporting the Jirai-Kei style to a T, Karen wears a dark gray colored frilled dress which is complimented with black heart-shaped buttons, a pink bow with a red jewel-like heart ornament on its center, and laces at the side of her skirt, her belt has a white cross at the center of her waist and pink-outlined hearts can be seen on each side, her detached sleeves compliment the rest of her design with belts tightening around her wrists and combining the red accents with the ones seen on the skirt. The design motif continues with a single fishnet sock on her right leg which carries a holster of sorts on her thigh and finishes with a pair of black boots with frilled socks. Karen wields a Maschinengewehr des Standschützen Hellriegel (also known as the Standschütze Hellriegel M1915) submachine gun. The stock is colored in dark purple with visible cracks which is covered with stickers in some areas, the end of its barrel shroud has a noticeable splatter (similar to blood) painted in pink, additionally, some small parts of the weapon, such as the water cooling cable, trigger, drum magazine and the cocking tube + lever are coated in a metallic pink finish. Around Guest, every trace of composure melts - she is completely, helplessly, embarrassingly in love.
