How do I get one?

if your sig says right... you only have a ninja and zelnogrard... both have NO tension equipment...

you need to get one of the next shinki/equipment for tension

- tsugaru
- ach
- yda
- fort bragg
- juvisy
- zyrdarya
- eukrante
- ianeira
- schemetterling
- tigris
- vitulus

if you dont have one of those... no tension for you

Fort Bragg is actually going to be my next purchase. So, to get a tension meter, you need a combination of a certain head unit/personality, and equipment? Thank you.

Not head/personality. Just a set of equipment.
