Gift items have their grade depending on the support characters. However, they can be categorizes as follows:
| Item Grade | Points | Support Character Reaction |
|---|---|---|
| A+ | +80 to +300 | Receives an extremely favorable item |
| A | +50 | Receives an extremely favorable item |
| B | +30 | Receives a good item |
| C | +10 | Accepts a so-so item |
| D | -10 | Angrily accepts an unwanted item |
| X | -70 | The item was received from the support character it is offered to, so it's rejected |
| Y | -30 | Support character gently rejects an item |
| Z | -50 | Support character firmly rejects an item |
Here is a few important note about gift exchange:
- Each support character starts with 300 points.
- When giving item to a support character, other support characters will lose 2 points.
- Each support character has unique expressions based on the amount of friendship points. For example, they turn their back on you when your bond is low, they face at you when giving item when you have a good bond, or they smile/happy when you are deeply bond.
- Some items have a special effect, notably "Wonder Flower" which make the support character forget about last trade. Hence, negate the previous trade result.
- Some items given one after another will boost the item grade to A+.
- Some Item grades are based on the specific place and time.
