Description: A technique meant to mimic the vision of owls. Flowing Senjutsu chakra to their eyes, the light bounces around the inside of the user's eye to hit the retina multiple times. Though it enhances eyesight tremendously, it does not pierce through solid objects or opaque chakra creations. Its sight capabilities pale in comparison to true Doujutsu such as Sharingan or Byakugan, as it cannot see outside the existing field of vision or give form to chakra; instead, it enhances clarity, normal viable sight range, and allows for telescopic vision. This technique affords users one of two things.

• In regular light: The user's vision becomes extremely precise. Tiny details jump out at the user, and even slight movements can be noticed. They can see and track movement of one rank higher than normal.
  
• In darkness: The user's eyes catch all traces of light from the surroundings, refracting it and bouncing it around the retinas; because of this, even the darkest areas can be seen perfectly, as if in regular daylight, so long as there is the faintest light in the area.
  

If utilized with another sensing technique, the user's optic nerves can combine their incoming information with an extrasensory perception to allow 'sight' beyond solid matter or even of chakra or other things, adding the ranges of this technique and the other sensing jutsu (any multipliers on range are applied after this addition).

Description: A technique that does not summon the Yachō owls, but rather their habitat. Yachō sage clansmen may have individual summons of their own, but all Yachō owls will refuse to comply with commands if this summoning is not active. This technique summons the snow, the permafrosted ground, the surrounding atmosphere....everything. A specific place in the Alpine Perch has been set aside for this technique's use. This technique is used to bring the only environment hospitable to the owls (that of Korigakure) anywhere, instantly.

Rank: S.

Range: Non-Applicable.
Specialty: Senjutsu.
Duration: Until dispersed or forced to retreat.
Cooldown: Once per topic.
Description: This technique summons the head of the Yachō Owls, who also happens to be their Great Sage. She is capable of telepathic communication (both ways with a willing party). Despite her age and stature, she is quite formidable. Being an owl, flight at any altitude and aerial maneuvers are effortless. Far from being a physical fighter, she can cast Fuuton jutsu by simply flapping her wings; A-rank has 6-post cooldown, B has 4, C and below is effortless. She can also use the S-rank Genjutsu: Nakigoe {Illusion Technique: Birdsong}, a specific-frequency auditory Genjutsu that reduces the reaction time of everyone in a 2-km radius by 2 ranks that isn't a member of the Yachō clan. She also uses a specific style of Katon known as Ice-Fire, which causes burns with cold temperatures; she can use B-rank Ice-Fire every 5 posts, C every 4, and D-rank effortlessly. At any time she doesn't have a cooldown active, she can cooperatively use her vast array of jutsu to assist her summoner, increasing the power of a cast jutsu by 1 rank (only once per summoning, costs 80 chakra). Despite being a tenacious fighter, she is, by species and age, extremely weak against Taijutsu. She has a bank of 600 chakra, and once she has exhausted it, she automatically ends the summoning. All of her jutsu are Senjutsu.
