I have been making a lot of Hunipop 2 videos for the past few weeks. Several of them could be helpful for those who want to complete some of the more difficult achievements in the game. So I decided to make this guide. Work in progress (starting with the most challenging acheivments)

Return the Nymphojinn to a satisfied slumber.
Return the Nymphojinn to a satisfied slumber on Incel/Femcel (Hard) difficulty.


The final boss can be tough, especially on hard, but as long as you make sure every girl has some decent items you should be able to beat it. Here is a playtrough off the boss on hard with 34 moves to spare:

Earn a 100% completion rate.
Earn a 100% completion rate on Incel/Femcel (Hard) difficulty.

To 100% the game you need to beat the game, max your stats and unlock every outfit. You don't have to get every piece of information for the Huniebee.

Unlocking the costumes is usually the hardest part. It can feel a bit random, but every girl follows the same pattern. Costumes are tied to date locations, and locations are tied to time of day. Armed with this information you can start targeting specific outfits to unlock. If you are having a hard time completing alpha dates after finishing the boss, you can turn off Alpha mode with the code "BETA 4 EVA". You can also unlock outfits in the endless-date-mode, which can be a good option if you are missing multiple outfits tied to the same location.

Successfully complete a Non-Stop date of 8 or more rounds.
Successfully complete a Non-Stop date of 16 or more rounds.


The Non-Stop date mode is one of the most challenging things in the game, but getting to date 16 is completely doable, my personal record is date #22 on normal. Here is my full play-trough:

Successfully complete 8 Alpha Mode dates.
Successfully complete 24 Alpha Mode dates.

It is easy to get trough Alpha dates with the right combination of girls and items. I usually bring either Zoey or Nora since they can clear Broken Hearts and pair them up with Suki or Lola since they have some of the easiest baggage to deal with.

My favorite item build is the Low-and-slow makeup build(Makeup Palette, Eyelash Kit, Powder Brush and Exfoliating Scrub) witch lets you generate more moves than you use, once its up and running.

Equip the other girl with support items like Lube, Candles, Plushy, Dolphin, butt-plug, etc...

I am currently at Alpha date #55 in Incel. here is a video of some of my recent dates:

Earn 5000 or more affection from a single token match.

Here is my item setup for big combos:

Top girl / Carry (Nora, Suki, Lola)

Powder Brush (+2 stamina on 4-of-a-kind matches)
Magic Wand (Doubles affection from Most favorite type)
Blow Dryer (Incresed effect from power tokens)
blue/green/orange Plush (turns broken hearts in to affection tokens of that color)

Bottom girl / support (Suki, Zoey)

Blow Dryer (Incresed effect from power tokens)
blue/green/orange candle (increas drop rate for that color)
Lube (All other date gifts costs 2 sentiment less)
Hair Brush (Increse the spawn rate of power tokens)

Successfully complete a date with both girls having maxed out passion, sentiment and stamina.

This one requires a bit of effort.
Filling up both Passion and sentiment takes a while, but the trickiest bit is to finish the date while keeping both stamina and sentiment at max. The easiest way to do this is to equip Lube on both girls and finish the date by playing a bracelet. They normaly cost 4 sentiment to play, but after playing double Lube, you can play the bracelet for free and finish the date without using stamina or sentiment.

Successfully complete a date wherein the girls become exhausted or upset at least 8 times between them.

The easiest way to get this one is to use the Breast Pump item which lets girls recover twice as fast when they are upset or exhausted(2 turns instead of 4).

Successfully complete a date with at least 20 moves remaining.

First off, if you are good at matching you can get this achievement on your first date of a new save.

If you want to get this on a regular save file there are plenty of items that helps you generate more moves than you use, like makeup palette, Exfoliating Scrub and Sweet Honeycomb(yellow candle). There are also items that lets you generate large amounts of moves at once, like the Chick Plush and Yellow Narcissisus(Flower).

Collect enough fairy wings to summon the Nymphojinn within 15 in-game days.

While not technically the hardest achievement in the game, it is definitely the one that requires the most effort, since you have to play trough the entire story to get it.

You need to complete 48 dates to collect all 24 fairy wings. Since you can go on 4 dates per day, 15 in-game days gives with 60 attempts to complete the 48 dates, which leaves you a margin of 12 dates you can fail or skip.

Towards the end of the game you might have to skip a few dates while waiting for the right pair to show up. Expect to do this up to 4-6 times, which leaves you a 6 dates you can fail and still get the achievement.

This is totally doable, but it is absolutely a challenge. I got this achievement while successfully attempting a "perfect game" with no failed dates. Off course, you don't have to finish the game in one sitting to get the achievement. And if you fail a date, it is totally OK to quit the game and try again. The game won't autosave until you move on to the nex pair of girls.

I am not going to make an in depth guid for the strategy right now, maybe another time, but here is some basic tips for clearing the game withing 15 in-game days.

• Allways talk to the girls to maximize your resources during the early game
  
• prioritize smoothies first
  
• prioritize unique gifts second
  
• prioritize S-tier items third (like plushies, Makeup palette, powder brush, lube, magic wand, etc ...)
  
• then prioritize shoes and other date gifts
  
• Buy as many permanent items at you can during the night before the shop resets in the morning
  
• Once you have a surplus of Hunie Seeds in the late game, you can start buying food for your dates to make them easier. I preferre food that gives you sentiment
