Yes, it's not required for you to have any hinata/haikyuu pieces for applications! We do recommend you have at least one work that is hinata/haikyuu-related, but our judging won't change much for not having more than one and we won't disqualify applicants for not having any.

Also, it's totally fine if you aren't a big account! All our apps are graded semi-blind (everyone is re-labeled as Writer1/Writer2/etc) with Mod Gumi primarily handling looking at the unblinded list in case someone needs to be contacted for application fixes/questions - so we really do not look at your following. We just care about how well you write/draw Hinata.
