Tenrai kan

Tenrai kan (天来勘; Literally meaning "Divine Perception") is the Kekkei genkai of the almost extinct Hairaru clan, which gives them the ability to perceive to the residual information of an object by touching it. By infusing their chakra into the sensory receptors all over their body, they can learn historical memories or sensations concerning objects they touch. For example if the user touches a flower, they may see a vision of the one who planted the flower, those who have tended to the flower, and other details. More experienced users can learn and understand everything about a person by touching them without the need of special education or long-term relationship. It works as if they have been with their touched subject all their life. However doesn’t understand thoughts or minds. The ability seems to be rare amongst the clan members and often all except those who came in contact with the ability considered it a myth.

Techniques
Butsuri-tekina ripurei (物理的なリプレイ, Physical Replay) This technique grants the user the ability to mentally and visibly project moments in time for observation.

Tenjō-kai no ōin (天上界の押印, Unworldly Imprint) This allows the user to voluntarily leave an imprint, either externally or internally. Excellent skill to use as a personal tracker.

Iryō-yō kenshutsu (医療用検出, Medical Detection) This technique requires a great amount of chakra to maintain. This grants the user the ability to learn a person's health. This is a great technique because a serious health problem that could be fatal could go undetected. However with this technique the user can see the cause and effects of any medical problem. Note: This technique informs the user of the medical details, but do not heal them.

Seishin hansha (精神反射, Psychometric reflexes) Grants the user the ability to temporarily learn skills and abilities from objects or people. In order to obtain the skill or ability once more they may need to touch the object or person which holds said knowledge again. Dekōda (デコーダ, Decoder)This technique allows the user to decipher and obtain the language of others no matter how very old or new it is. The user may posses an object who belonged to those that spoke the language or a living (in some cases non-living) being that speaks said language.
