Hakochi

Two numbers define Hakochi, a Common blocker: Block 80 and Jump 75. Everything else is modest or poor, with Serve at 15, Speed at 20 and Spike at 40, so it is slow to move and weak when it attacks. The stat total is 375, which is 44th of 45 styles, and the site's formula (built on the wiki's estimated stats) gives it a D tier overall score of 46.9. The role view is kinder: it is a B tier blocker (69.3, 15th), a C tier setter and receiver, and a D tier spiker (43.8, 44th).

If you want more of the same from a higher rarity, Hirakumi pushes Block to 100 with Jump 100, though it is a Godly style with Speed 15.

Hakochi has no special move, no Mastery rewards in the data and no limited window, so it is simply always in the pool. The wiki gives odds only for the whole Common rarity: 62.5% on a normal Style Spin and 0% on a Lucky Style Spin, so a Lucky spin can never produce it.
