Description: The Gentle Fist is a form of hand-to-hand combat used by members of the Hyūga clan of Konohagakure. The fighting style itself is one based on redirection, quick strikes, parries, and counters. It inflicts internal damage through attacking the body's Chakra Pathway System, subsequently injuring organs which are closely intertwined with the area of the network which has been struck. To do this, the user surgically injects their own chakra into the opponent's chakra pathway system, causing C-Rank internal (True) Damage. If aimed right, this can cause damage to surrounding organs, as well.

By employing the use of the Byakugan they can target the tenketsu to actively seal the opponent's reservoir. These 361 nodes are key gate-keeping interceptions in the chakra circulatory network, and can be actively opened or sealed by Gentle Fist users. The affected person's chakra flow can either be increased or disrupted completely, preventing them from using techniques or making them use more doing so. Since blocking a tenketsu takes only the slightest tap, the user can focus their entire attention on striking quickly and numerous times in a short span of time.

As Gentle Fist users are able to open tenketsu, this is beneficial to those they do it for. For every 32 tenketsu opened, the afflicted person gains an additional 15 chakra points. This effect last five posts, and after they're done the target suffers an exhaustion penalty of one minus to all physical stats for two posts while they recover. This effect can also end early if the afflicted person burns through the excess chakra they've been given.

When closing tenketsu, every tenketsu that's sealed drains 1 chakra from the target. Tenketsu remained closed for the remainder of the topic after which they will open back up. They can also be forcibly opened by an outside source of chakra (i.e a bijuu or curse seal, or any outside source of chakra being channeled into the user specifically to unblock the Tenketsu), though this requires that source of chakra to equate to the maximum chakra that's already been locked away from the user. If all 361 of a single person's tenketsu are sealed they fall unconscious.

Additionally, Gentle Fist can be used to perviate chakra-based substances, be it webs, armors and even barriers of up to B (in rank and/or durability). While in use, Gentle Fist boosts a user's Speed by a + and Coordination by a ++. Hyuugas are also able to stun opponents for one post based on how many strikes they've landed (and tenketsu they've sealed), in comparison to the opponent's Constitution.

E-tier Con: 4 hits
