Effect[ | ]
Nanako's Hyper is Deploy Bits. When used in a battle, the player gains a total of +7 points distributed at random to their ATK, DEF, and/or EVD stats.
Strategy[ | ]
Deploy Bits gives Nanako surprise potential as her low HP and average ATK make her a character who isn't as suited to fighting as to defending. The gains from her Hyper can alter the current battle depending on her fortune with the +7 overall stat distribution.
Quantifying this Hyper leads to the conclusion that the average gain to each stat would be +2.33, leaving Nanako with a statline of +2/+4/+3 (with one added point given to a single of the three). Not only does this guarantee that she avoids anything below a 4, but it also allows her to survive an ATK roll as high as 12, which can be achieved under certain circumstances like extreme stacks of 's passive, 
Accelerator or 
Accel Hyper. While +2 ATK is also nothing to scoff at (and it can potentially go higher with some redistribution), it, in a similar vein to 
Hyper Mode, is not enough to make reliable offensive plays unless an enemy is at low HP or the player is desperate, at least when layered atop Nanako's neutral offences. This leads to its best use case being as a surprise tool when an enemy tries to pick her off or otherwise rob her, as it can quickly lead to the tables turning.
Be careful with using this Hyper at 1 HP, as any stat boost applied to DEF is effectively wasted. It is best to use this card while at 2 or 3 HP in an attempt to defend against strong attacks.
