Presents
The Diamond Marker Pen can be given to her (this uses a special conversation option rather than the usual "Give her a present") and causes her to give you the Spicy Fried Chicken in return.

Sidequest
Diamonds Soldier has a sidequest where you talk to her about her concerns. The details for this are currently unknown.

Completing this sidequest gives the achievement "About Loyalty and Future ".

H-scenes
Diamonds Soldier has two H-scenes, both reusing artwork from Succubus in Wonderland:

The first is a breastfeeding handjob, which can be obtained by going into the Communal Bath between 7:00 and 8:59 on Day 3 and talking to her twice. This gives the achievement "Diamonds' Healing Method".

The second is a group scene with the other card soldiers, which can be obtained by going into the Communal Bath after 18:00 on Day 3. This gives the achievement "BADEND3: Hero Soaked in Milk".
