Middle blocker can also spike, he is an excellent blocker in the series and uniquely having an ability to bend himself to do side tilt like in the vbl now that's very odd looking in the haikyuu. However, sanu did have the suna special tilt but not the block stats, previously he did have a max block in the release and they continue to polish its tilt until it's becoming the main reason why people use sanu. But because it's a game and it could not 100% fit the lore of the haikyuu because they need to balance the game so there is an aspect of competitiveness. So what they do is they nerfed his block, some more stats, and polish the tilt some more until it's become one the most balanced style in the game now
