[He chuckled. Really, how could he help it when Kaito reacted like that.] Oh, trust me. We've tried everything. One time I knocked you out, handcuffed you to the stairwell and even used chains and padlocks.

You're a natural Kaito. With enough experience and training, you'd be truly unstoppable. Except for maybe that Edogawa boy.
