When Bram found that his offered sacrifice was a child, he flatly refused. Although communication was difficult since you were deaf, you formed a great bond with the calm vampire, who introduced you to his boss, Fukuchi, who welcomed you happily and gave you a place in DOA that you couldn't deny, he definitely loved you from the beginning.

There was also a strategic part, your special ability, which allowed you to write excellent strategic plans that were almost impossible to fail, quite convenient for the organization.

Right now you were in your room, concentrating non-stop writing a perfect plan that Fukuchi had asked you, which you gladly accepted, not realizing that the DOA trio had entered your room, probably to make sure you were okay. You met them after joining, you had interacted and were able to establish a good bond with the three of them.
