"Enjin-Yaburi　apply (円陣破ー崩し)"

This is essentially a technique used when surrounded by enemies and threatened.
You pretend to be frightened first, hand a sword to the enemy.
You show yourself weakly and bring the surrounding enemies as close as possible.
The moment the enemy tries to take your sword, you drawing sword and rotate.
You cut as many enemies' eyes, arms, shins and so on as possible.
And you escape instantly.

An enemy can not be tracked (or has fewer people) , because there are multiple injured companions.

In this movie, it is not the original shape itself, since it extracts only drawing sword part.

This skill is important to acting skill.

The image of the samurai fights squarely.
Samurai fight fair.
It is certainly one aspect of the samurai. But not all.

It is also a samurai to use all means for the mission.
Samurai is never stupid.
(Although there were such samurai, too)

They used intelligence and plot.

ENBU: Daihan（代範） Takizawa Dofu（滝沢 洞風）

天心流兵法 世田谷支部の稽古より。
まーこ先生こと、滝沢代範による円陣破（えんじんやぶり）の崩し。
本来は怯誘返（おびえさそいがえし）として用い、円陣破なので、囲みを抜けるまでが技法ですが、これは抜刀部分のみ抽出した形になります。
最後のはおまけ。
