Though he is a genius, he is a dou user. So he won't be able to use that ability. What I'm thinking is that he is going to aim to put Miu in danger in order to get Kenichi's real strength drawn out and fight him. Beserker looked very interested in the fact that Kenichi dispatched with him at ease when Miu was in danger after taking two punchies. And it looked as though Beserker was really just testing out Kenichi from the start since he has heard so much. I don't think Beserker has gotten serious with Kenichi yet and is just testing to see how strong he is. And after seeing Kenichi fight even with him, take two punches while being distracted and then dispose of his battle without another thought or hesitation, Beserker is itching to get Kenichi to fight with all his ability and he may have found the way to get it with putting Miu in danger.
When you cross paths with a beast, are there any guarantees... that you won't be mauled by it
