[Western Crossover] The Bat Kid Who Doesn't Typical Fight for Attention

For the past 15 years, Finno has had only one goal. To kill his "master." He was prepared to bear all the consequences. When he saw the other's torn body, he believed his mission was complete. Bruce has always felt at a loss about his newly adopted child. The child has been through too much, yet seems to need so little. So Bruce is willing to pay him a little more attention and treat him a little better. Besides, the kid is smart, sensible, composed, and level-headed, and he listens to other people's advice. He's far less trouble than the other little brats, so there's nothing wrong with giving him a little attention! The children of the Bat Family silently raised a third finger at their old Bat Dad. The new kid had already risen to a position second only to the butler. As for old Bat Dad? Who cares about him! Recently, the tracking device on one child's person has been constantly jammed. Considering the kid's own personality, Old Bat Dad immediately figured out that the other little brats in the family had planted too many surveillance devices! Sure enough, when he brought it up, the kid handed over a stack of devices, while the little brats looked away guiltily. Old Bat Dad gave a cold laugh, already planning at least a week of "hell training" for every one of them. Until "B," the kid said, taking one off himself and holding it up to him. "This one's yours, and it's been interfering with the tracker too." The butler wiped the silver tray in his hands and casually pulled out a rocket launcher, planning to give the biggest bat in the house a thorough wake-up call. Reading guide: 1.
