You may think i "don't know what im talking about". That's what you want to believe, Im not here to prove you wrong.
Since i got max affection on all the girls prior to the update, i dont need to buy that many affection gifts.
I spend my time gathering money to just upgrade my girls. I dont calculate exactly how often i need to check back. I just play the game and check back when i remember, which on the hour is easy enough for me to remember. I can tell you that with my "mostly" maxed army, its working for me great.
Lets list what kobans can do:
For 25 - Refill your battle points (Can get cash from wins)
For 7 - Can restock items in Shop
For ?? - You can finish a mission instantly (prices vary) which drops affection items
For 900 - You can spin the gacha and get affection items (and a girl)
For 2 - You can collect all cash from girls in harem
For ?? - You can instantly upgrade a ready girl
For 40 - You can refill your energy points (for the story) *
*Don't do this one, there is no rush to finish the story.
Hope i didn't miss anything. Not gonna mention the pay 300 koban for instant collecting, because thats new
