I am a low level guy who is in the daily contest to try to get more girls. Approximately how many fights, against Dark Lord or Ninja Spy does it take to get a girl to join your harem? What level or adventure city do I need to reach to generate and win kobans? I hate to waste Kobans to replenish energy units, since this game takes energy unit away so quickly the same with Combativity units....both take so bloody long to add. Sorry I am not willing to spend real $$$ for kobans when I see how fasts and how many I need to spend on energy units and combativity units. I have been trying to save my kobans so I can play epic pachinko and win a girl. I do not see any other way to get girls to join me. I have won one girl against the Dark lord zero from ninja spy. Is there any trick to getting more girls or Kobans?
