Resolves based on Vstats numbers. https://www.vstats.jp/

Watch hours are calculated by taking average concurrent viewers for a stream and multiplying by time. For example, a stream with an average of 10000 viewers that lasts for 2 hours would add 20000 watch hours to that vtuber's watch hours for the year.

Non-live viewership is not taken into account.

All hololive members of all branches (EN, ID, DEV_IS, etc.) are eligible.
