The birthday skeleton will provide the requested photo with his usual THE CONTRACT IS SEALED enjoy your birthday gift and the weird creeping feeling of having a skeleton wake you up from your sleep, Jun!

As for the gacha:

Werewolf - Congrats you're now a werewolf! On nights of the full moon, you will turn into a large wolf. You also gain other abilities such as enhanced strength and senses, and the ability to shift into a wolf (once you have it under control). This can last one week or be permanent (or you can choose to opt out altogether if you rather not).

3 point random power - Jun now has slow aging (you take four times as long to age).

Your rollover sidequest gachas have now all been cleared!
