B-ka (B香) is a main character seen in the second part of Shuuen no Shiori Project.
- B-ka has gentle, purple eyes and blonde hair with an ahoge (a single standing up strand) on top of his head. It was revealed that he had bought a school uniform that was too big on him, claiming that he would grow into it eventually, but the sleeves on it are still too long for him. He is generally small, even shorter than A-no, and he has a more feminine face than her as well.
- B-ka is a timid character who tends to stutter a lot when speaking. He is quite a gentle boy, and dislikes fighting.
- Gentle Ghost Story
- Bokutachi Days
- He has "Double Teeth" (八重歯 Yaeba), which are similar to the fangs of a vampire.
- When found dead and decapitated along with everyone else, minus E-ki, his legs had been shown to match C-na's upper body.
