The information at the top of the screen shown in Figure 1 above consists of three main parts
There is also a gauge on the bottom of the screen as seen below in Figure 2
Normally, this gauge says Power, but in certain cases it can read something else (eg., Ruriko's says Denpa, which means Electric Charge). The gauge starts out empty (i.e., transparent) and the counter on the right is set to 0. Every attack that you do against your opponent will build up this gauge (multiple hit combos will cause a faster rate of increase) and the number will increase from 0 up to 9, indicating how many "Full Bars" you have stocked. Each character has special moves called Hissatsu waza (Certain Kill Technique). A more powerful version of this move (referred to as an EX version) can be done using 1 full power bar. There is also the Chou hissatsu waza (Super Certain Kill Technique) which requires 3 full bars.
