Hana's position was given up when Yoko repositioned to the side. However, she wasn't concealed the best to begin with. The cube was fairly large, but not big enough to entirely cover Hana from view unless she ducked down while moving as she had. However, now that she was spotted, and closer to her target, it was time to proceed with her plan.
The cube shrunk and dropped to the ground as it returned to its normal size. Hana could recover it later - for now it was sufficient that it had done its job. Yoko hadn't wanted to commit her puppet to fighting the cube, which to Hana indicated she wasn't willing to test it's strength in that manner. That worked perfectly.
As she readjusted her course to pursue Yoko, the puppet came in at her from the side. It posed a minor thread, but had to be deal with or she couldn't get at Yoko. Taking out Yoko took out Wanimon, or so Hana's puppeteering knowledge indicated. She rolled another one of the metallic die in her fingers, and as Wanimon approached, Hana flicked it towards the puppet.
Hana had no intention of activating her jutsu this time, but now Yoko knew that Hana could make that tiny cube into a much larger projectile. Hana was gambling that she'd chicken out on having Wanimon confront the cube and change Wanimon's trajectory, thereby giving Hana easier access to the puppeteer.
With the cube away, Hana reached behind her and plucked a quartet of kunai from her pouch, one of which had a gray tag hanging from the handle. Once they were in hand, she jumped into the air and flipped (a bold choice considering her outfit) and flung the projectiles towards Yoko.
With the kunai away, Hana performed a single handseal and activated the gray tag which erupted into a cloud of smoke an obscured Yoko's view - but she had likely already seen the best part by then. Unlike Yoko, who would be unable to see Hana, Hana was not impeded as much. The strings she used to control Wanimon hummed for her ears and led her right back to where Yoko was at.
So she dashed towards her at full speed. fingers blurring in a flurry of motion as she prepared one of the other techniques she knew. From inside the smoke, she activated a capture fuuinjutsu that could seal movement, and might very well lock Yoko down and make it very easy for Hana to finish their little bout.
