Full Plot Summary
"DaDaDa" by Group Tamashii
Oga learns that the man who was split in half is a sort of living teleporter named Alaindelon. He also finds that Hildegarde has lied to his parents in saying that she is his wife and Beel is their son, so he can't back out so easily. Also, Hildegarde mentions that even though Beel's electric shocks are painful, they get even worse when he is pulled away from Oga, and at 15 meters or more they could be fatal. So while Oga is still trying to find someone to pass off Be'el before he gets shocked to death, he also tries to keep the baby within a maximum of 15 meters while fighting the punks who try to challenge him.
