Adding to This.
If you plan to have a Fair-Play on the first playthrough Earn Bits to at least 3.5k so that you can Infinitely train Str, and Nim, in New Ark, both is a Massive part of the game and will help in nearly every Aspect.
The Min for bits is 2.5k for the Condo and entrance, after that you can either take A Permanent Gym pass, or a Temporary one, if you get tired you can just walk to the Condo and rest, then repeat the Process.
This will also Trigger Fawn, which is one of the Romancable NPCs, who is into Domming, or BDSM, for a simpler term.
2nd Rinny, will teach the Skills drain kiss, and shock which are Skills that will help for big fights like Mistrya, or that Flesh thing at the elevator.
Shock, can Stun enemies and deal Stamina Damage.
Drain Kiss, Deals both Stamina damage, and Erotic damage, but has no Debiliations.
