Byakugan [Doujutsu]
The Byakugan is a special eye condition that can be awakened by some members of the Hyuuga Clan. Any and all individuals who carry the bloodline's power have white eyes, even when the power is not active. Once activated, the nerves around the eyes will be visible under the skin, making even the most composed and beautiful face suddenly unsightly and intimidating.

Byakugan (Su): The character can activate this ability as an attack action that costs 7 points of Chakra every round to maintain. The character gains an insight bonus to Defense, Initiative and High Speed Sight, and the ability to constantly See Chakra.
He is also able to see through and thus ignore lighter forms of concealment, such as smoke or mist. The character may concentrate for an attack action while his Byakugan is active to See Through Chakra for as long as he concentrates (as per the technique) and his Byakugan remains active. Deactivating this ability is a free action.
High Speed Sight (Ex): While the character's Byakugan is active, he gains a high-speed sight quality as above.
Keen Sight (Ex): While the character's Byakugan remains active, he gains an insight bonus to Search, Sense Motive and Spot checks.
Combat Insight (Ex): The character gains an insight bonus to Reflex saves and attack rolls while his Byakugan is active.
Telescopic Eye (Ex): When concentrating to See Through Chakra, the character can also spend a swift action to gain the ability to see through 1 foot of stone or concrete, 1 inch of metal or up to three feet of wood, plaster walls or dirt per 5 levels, for 1 round. He also suffers a penalty to spot checks only every 50 feet instead of every 10 feet.
While this ability is active, he cannot apply his Dexterity bonus to defense against melee attacks, and suffers a -4 penalty to melee attack rolls.
Tenketsu Sealing (Su): Up to four times per day, the character may activate this ability as a swift action as long as his Byakugan is active. This ability enables the character to directly see the chakra coil system of anything it focuses his eyes on.
The tenketsu sealing ability grants the character a +1 bonus to attack rolls made in any jyuuken stance, and every successful jyuuken attack deals 1 tenketsu damage to the target unless it succeeds a Fortitude save (DC 10 + ½ character's level + character's Wisdom modifier). On a confirmed critical hit, the jyuuken attack deals 2 tenketsu damage (or 3 if the character's critical multiplier is x3, 4 if it is x4, and so on).
Tenketsu damage to chakra created constructs and objects does not apply—instead, each point of tenketsu damage dealt deals 1 point of damage to the target. The ability lasts for 1 round when activated.
Enlightened Byakugan (Su): While his byakugan is active, the character can only be flanked by creatures of his level or higher, and can no longer lose his Dexterity bonus to defense unless caught flat-footed or immobilized.
In addition, when concentrating to use his Telescopic sight, he may make a spot check in any direction without needing to move. Other conditions that may cause the character to lose his Dexterity bonus to Defense, such as being feinted against, are still applicable.

GM note:
The Hyuuga clan is the perfect template to create clans and is generally viewed as the norm for the Bloodline System.
Most clans (including Uchiha) are Intermediate and/or minor bloodlines,
Major bloodlines are extremely rare and usually carry with them some sort of XP modifier applied to those possessing it)
