Engagement
A typical post picks up 11K interactions against 1.9M followers, an engagement rate of 0.568%. Measured over 10 original posts, its engagement rate beats 98% of 3,739 tracked accounts of a similar size. Comparing inside a size band matters here: engagement rate falls as accounts grow, so a raw rate would mostly just re-measure the follower count. Posts are seen about 202K times each, and 5.35% of those impressions turn into an interaction. That is about 10.6% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.4 posts a day over the last 30 days, though only 30% of days saw any activity at all. Most posts go out around 12:00 UTC, and Sunday is the busiest day of the week. Of the 10 posts sampled, 100% carry an image or video. The account's strongest tracked post pulled 110K interactions, about 10x its own typical post. Recurring topics include #nikke, #c108, #comiket.

Compared with accounts its own size

On engagement per impression rather than per follower it beats 96% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.

Posting timing
This account posts most often around 12:00 UTC, and Sunday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.
