Tatsuya himself would step back as Ami approached, retreating 5 meters.
Puppets were an interesting subject. Most people didn't really understand how subtle a weapon they could be. For instance, Tatsuya himself had once asked his mentor, Shimano Nara, why they made puppets that were mainly humanoid in shape. Wouldn't it make more sense to make it with a dozen sword arms that shot kunai out of every available orifice? The thing is when someone sees something human-shaped they unconsciously assume that it's going to move as a human does, and when it comes to puppets that simply isn't true. If a human was leaping through the air brandishing a scythe it would be impossible for him to suddenly move backward in mid-air, reversing its course to avoid an attack. But since Tatsuya was the one in control, steering the puppet from behind, he could easily make that correction.
Once Ami was airborne and bearing down with her sword the puppet would pull back through the air, out of the reach of her blade. It would lift its scythe over its head and bring it down like a hammer while Ami followed through with the swing and was falling from her jump. She could attempt to defend herself of course but mid-air post-swing wasn't exactly the most stable position and of course, the spear-like length of the scythe, by design, kept the puppet out of reach from a parry from a more traditional sized weapon like a katana.
