Krownoichi

"Krownoichi" is an archetype consisting of  monsters. Most of the members of this archetype are, all of which have a  of 4.

Etymology
"Krownoichi" is a portmanteau of "crow" and "kunoichi", the latter of which is the term for a female ninja. All the Pendulum members of this archetype are named after a weapon in ninjutsu, followed by a rank in Judo that references its original. Ironically, in the case of the latter, the members of this archetype that follow this theme with the highest Level are usually more powerful, yet the lower-numbered rank in Judo is traditionally the highest rank.

Playing Style
All of the members' monster effects include an that treats them as members of the "" archetype, while all of the Pendulum members'  include such a condition that treats them as members of the "" archetype. For all the Pendulum members of this archetype, they have both a restriction that prevents the player from unless they have a "Ninja" or "Ninjitsu Art" card in their other, and an effect that changes the Pendulum Scale to match their original , should they control a "Ninjitsu Art" card other than a Pendulum Monster. The only exception in the case of the latter is "Katana Yonkyu", whose Pendulum Effect can make its Pendulum Scale 10.

Many of the Main Deck monsters of this archetype have an effect that, should they be removed from the, lets the player activate one of their following effects: add a "Ninja" monster from their to their hand (other than a card with the same name as the removed "Krownoichi" monster), or  1 "Ninjitsu Art" card directly from their Deck. All members that have this ability have a restriction that only allows the player to use one of the removed monster's aforementioned abilities per turn, and only once that turn.
