Kiyolancer

http://fate-go.cirnopedia.org/summon.php

Thats all the JP banners, im pretty sure Kiyo has another rate up next year though

Yes, this year's summer event will have a rerun next year. Unfortunately, next year's summer event will be right afterwards, so you won't have much time to save for that one if you blow all your quartz on this year's rerun.

If you are just hoping to get kiyolancer because you need a Buster single NP lancer, try Vlad III in this coming Halloween, he also can do a lot of damage.
