1. Get 1 keystone or 10 keystone pieces. you get keystones by
- daily reward by completing 3 hard mode stages (just skip them) for 1 piece
- by weekly reward completing 15 hard mode stages (skip them as well) and participating 10 PvP matches (doesn't matter if you lose or win) for 6 pieces.
by completing daily and weekly you get 13 pieces in a week total
- you get keystone pieces by exchange points from limited banner. after the banner has ended you get at a 1:1 ratio.

2. Bring them in the craft section. select the "花弁" node. this one will craft presents for you waifus to raise the affection level. at this point it is enough to get a present but you can add a̶n̶ ̶a̶d̶d̶i̶t̶i̶o̶n̶a̶l̶ 5 keystones to increase it quality or 20 keystone pieces. sometimes it appears randomly but if this one isn't available select "煌めき" node instead but be warned because of RNG you get something else.

Tip: Use a quick craft ticket, called ブーストチケット, to get your present immediately. Quick craft ticket can be purchased from the shop for 30000 credits.

3.1 Go to Cafe aka. Dorm. select the present icon to open up the present icon box, get the present you want to give and drag it to your waifu. Pay attention to their icons pop up when you give it. 🙂 icon give them small amount of affection points, icon give them moderate amount of affection points and a icon give them a large amount of points. Also don't forget to tap on the characters to also get affection points (Thank you guys in the comment section for this tip [厲害] )

3.2.: Also make sure you also raise the affection level in the schedules section by using schedule tickets.

4.Give present until she reached l̶e̶v̶e̶l̶ ̶8̶ until they reached a certain level, which you can see in the (sloppy maded) affection level chart below. .Go to momotalk, chat with your waifu to read through the story until you c̶o̶m̶e̶ ̶t̶o̶ ̶t̶h̶e̶ ̶l̶e̶v̶e̶l̶ ̶8̶ come to this reward which you can unlock the Live2D function and got a nice amount of gacha crystals too.
