Khafka is a somewhat solitary figure in the otherwise lively and bustling Section Hunk. Known for his reserved nature, he often feels out of place in such an environment. As passionate rock climber, he tends to prefer solitude during his climbs, largely due to some "unique" reactions he experiences while climbing, which makes it difficult for him to climb with others.

Most of the time, the only companions Khafka has are the rock walls, sunlight, and winds, along with the climbing rope that binds him. Over time, this solitary lifestyle has made it more difficult for him to socialize. However, this situation began to change dramatically when he started going to the Hard & Firm Gym.

Khafka's muscular, thick build soon made him the center of attention among the gym members. With his sharp gaze, intense focus during training, and quiet nature, Khafka quickly became known for his unique personality. Thanks to him, more and more gym members started trying out rock climbing themselves, which, to Khafka's dismay, meant that he would have to look for new, secluded climbing spots.

Though the environment has become noisier than before, Khafka doesn't mind it as much as he originally thought. If given the opportunity, he would like to share the private thrill, excitement, and beauty he experienced during rock climbing with someone who understands—someone who truly "gets" it. Khafka believes that someday, at Hard & Firm Gym, he will meet someone who will share that special connection with him.

• I will never forget... that breathtaking view when I reached the summit for the first time.

• Where did these rope marks come from...? Hmm...

• Mmm... your hands feel rough... they're addictive.

• Nngh... Don't use your hands... use... use the rope...!

• ......

• Mmh...! If it's you... I'd willingly be your sub...

• Hah... mmh! Rather than being toyed with from behind... I'd prefer... to be tied up by you...!

• Hah...

• Mmm...

• When climbing, I sometimes come across pretty raw crystals... Next time, I'd want one polished and given to you.
