Substitute Samurai #1

This is the best that I can do on a short notice with limited time at my disposal. This puzzle is generated by JSudoku with several additional clues by me.

Rating based on required solving techniques: Extra Hard
My personal rating based on actual solving: Hard

Except for a single non-basic technique this Samurai is pretty straight forward.
Below the code you can find a four step hidden hint regarding the non-basic technique. Select a step to read it.
If you do not know this technique, it is time to learn it. Hint 1 includes a URL.
It is only a tiny tick more difficult to learn than an X-Wing is and often easier to find.

Hint 1: The non-basic technique is a 2-String Kite


Hint 2: There is a 2-String Kite for 3.


Hint 3: There is a 2-String Kite for 3 in grid 5 (the bottom right one).


Hint 4: Pencil 3 can be eleiminated in g5:r2c5. Here a picture showing the 2-String Kite

Alternate hint 1: There is also a skyscraper on same digit and location, which is probably easier to spot.

[Børge]

JC, I beg to differ.
For someone unfamiliar with these techniques, I think that it in this special case it is more difficult to reason out the logic behind your alternative.
For the records, here the complete picture.

[Jean-Christophe]

Well, the logic is exactly the same, but personally, I find it easier to spot the pattern I mentioned in particular since: it's confined in two adjacent rows and is almost an X-Wing

Note: The skyscraper eliminates 3 from both r2c5 and r5c4 at once

[Børge]

What I meant by logic is the reasoning behind the elimination(s). As with many other things in life, personal taste factors in.
I surrender to your logical eliminations (sure you not have green blood?) and have updated the complete picture.
