This is how a real-life NINJA deals with multiple attackers
The Bujinkan is an international martial arts organization based in Japan and headed by Masaaki Hatsumi. The combat system taught by this organization comprises nine separate ryūha, or schools, which are collectively referred to as Bujinkan Budō Taijutsu.

How to become a Ninja:
Despite the murky history of the ninja, many agree that the ninja possessed great skill in stealth, combat, and agility. Constant awareness of one’s surroundings is the common foundation shared by these abilities.
The question is, which path do you want to take towards your interpretation of being a ninja.
If you prefer a way of ninja that is close to how traditional ninjas were, you can consider training in Bujinkan, Genbukan, or Jinenkan.
If you prefer a modern interpretation of being ninja, an eclectic combination of Parkour, stealth and martial arts skills would be suitable for you.
A ninja or shinobi was a covert agent or mercenary in feudal Japan. The functions of the ninja included: espionage, sabotage, infiltration, assassination, and guerrilla warfare.
Their covert methods of waging irregular warfare were deemed “dishonorable” and “beneath” the samurai-caste, who observed strict rules about honor and combat.
Superhuman or supernatural powers were often associated with the ninja.
Some legends include flight, invisibility, shapeshifting, the ability to “split” into multiple bodies, the summoning of animals, and control over the five classical elements.
These fabulous notions have stemmed from popular imagination regarding the ninja’s mysterious status, as well as romantic ideas found in the later Japanese art of the Edo period.
Magical powers were sometimes rooted in the ninja’s own efforts to disseminate fanciful information.
For example, Nakagawa Shoshujin, the 17th-century founder of Nakagawa-ryū, claimed in his own writings (Okufuji Monogatari) that he had the ability to transform into birds and animals.
