Here’s a fun take for you: in Japanese its 月曜日、火曜日、水曜日、木曜日、金曜日、土曜日、and 日曜日, which translates to basically moon day, fire day, water day, tree day, metal day, earth day, and sun day— although it’s really celestial bodies, the very same mentioned in another comment (e g. Mars is the fire star, Tuesday).
It’s supposedly derived from Chinese, though they probably got it from Romen influence given similarities.
Anyway, the eighth day probably needs to be 天王曜日 (which is basically heavenly king day) or 海王曜日 (sea god day, aka Neptune) but I’m unsatisfied with that. Plus, honestly it’s way cooler as an elemental theme so my vote is 電曜日, denyoubi or electricity day, in honor of Pikachu. That day would be super effective.
