Nagumo

**Nagumo** (南な雲ぐも, *****Nagumo*****?) is a major supporting character in Sakamoto Days and an old friend of Taro Sakamoto. He is also a member of the Order, a group consisting of the strongest assassins in the JAA. He is first seen paying a visit to Sakamoto to inform him of his bounty.

## Appearance

Nagumo is a tall man with short black hair and large, dark eyes. He is seen wearing a polo shirt with a large trench coat as well as black pants and formal shoes. He also carries a briefcase around on his back, which in it contains his signature, large, swiss army knife-like weapon.

### Tattoos

Nagumo has many tattoos, most of which are hidden by his clothing. His tattoos have mathematical inspirations, in particular, referencing the Golden Ratio.

Tattoos shown include:

1. On the left side of his neck, he has a marking of the Fibonacci Spiral.
	* The growth factor of the Fibonacci Spiral is the golden ratio, ~1.6180.
2. Two rectangular tattoos on both his hands, another reference to the golden ratio.
3. The formula

# ∅

{\displaystyle \varnothing=\sqrt{1+\sqrt{1+\sqrt{1+\sqrt{1+\sqrt{1+\sqrt{1+\sqrt{1+}}}}}}} }

 on his right forearm.
	* This is likely an infinite sequence of nested square roots which can be resolved to ~1.6180 (the golden ratio), though it lacks the

	{\displaystyle \lim\_{N\to\infty} }

	 formula that should precede every radix.
4. 5 rectangles with different designs (and the third and fifth of which are black), next to the formula tattoo.
5. The symbols, '2', '∅', '1' and '%' on his index finger, middle finger, ring finger and pinky respectively.
6. A snake coiled around his lower left leg.
7. A swallow on the right side of his right leg, just below the knee.
8. An impossible shape on his shin, below the swallow tattoo.
9. A square made of various spaced lines and curves on his right thigh.
10. A mandala-esque pattern on his right shoulder.
11. A pair of praying hands on his left pectoral.
	* Likely inspired by the *Praying Hands* drawing by Albrecht Dürer.
12. What appears to be scripture on his right bicep.
13. A line or lines which intersect, wrapping around his left posterior/anterior forearm.
14. A patterned, isosceles triangle on his left posterior forearm.
15. A rectangular tattoo on his right tricep.
16. An unidentified tattoo on his left bicep.
17. A wing-like tattoo on his left waist.
18. An unidentified tattoo under his left armpit.

## Personality

Nagumo's most notable traits are his laidback attitude and constant smile, which seems to be impossible to wipe off his face, and his incredible talent in annoying others around him to the point of them wanting him dead. He is easygoing and carefree, even in the middle of an intense battle, claiming to enjoy the wind in his hair as he stabs a man in the arm. He is also very playful with his opponents, evading and tricking Minimalist, a hardened serial killer, before handing him a dice to decide which of his blades he'd die by.

## Skills & Abilities

**Overall Skill Level**: Nagumo is a member of the Order and one of the strongest assassins in the JAA. Granny Miya stated that he is currently stronger than Taro Sakamoto due to the latter's physical prowess being at only thirty percent of what it used to be because of his five year-long retirement. Kindaka also stated that Nagumo has the potential to be a future leader of the assassin world, alongside Sakamoto and Rion Akao.

Kashima, a powerful assassin working for Slur, classified Nagumo as an S-rank target on the hit list he made, and Gaku, one of Slur's strongest subordinates, acknowledged him as a difficult opponent to go up against during their fight. Even Sakamoto, "the legendary hitman" himself, stated that Nagumo wouldn’t lose a fight without a reason.

**Master of Disguise**: Nagumo can copy other people's appearances perfectly in an instant, which he used to fool Lu Shaotang by disguising as Sakamoto. He can also disguise others, including significantly altering someone's body shape, such as disguising the fat Sakamoto as his wife, Aoi. When disguising Sakamoto, Nagumo says the disguise would only last for twenty four hours.

**Master Combatant**: Nagumo is an extremely skilled and deadly individual, as he prefers to use bladed weapons in battle. He was able to kill Minimalist, an A+ ranked serial killer, with ease and render a man completely unconscious with just his killing intent.

**Expert Marksman**: Nagumo can use firearms with incredible proficiency. He ranked 4th place in the top 10 greatest shooters of all time at the JCC, having scored 84 points.

**Morse Code**: Nagumo can use morse code, as shown when he uses the signal lights of a moving vehicle to tell Shishiba that he was "killing".

**Keen Intellect**: While always seen with a smile on his face, Nagumo is a very insightful person. He quickly deduced Kindaka's theory of there being a spy within the JAA's organization without the latter even saying anything. He was also able to quickly notice that Erio Muto, a JAA executive, was a spy working for Slur.

* **Poison Knowledge**: Most likely due to his upbringing as a spy’s apprentice and his training at the JCC, Nagumo is very knowledgeable of how poison works and how to adapt to it.

**Enhanced Speed and Reflexes**: Nagumo is capable of moving at extreme speeds, being fast enough to instantaneously disappear from a person’s sight. He can move so quick that he managed to catch even Shin, a trained assassin and clairvoyant, off guard, as well as decapitate Minimalist in an instant. Assassins working for Slur were unable to pinpoint or react to him, even as he sat on top of and inside their vehicle and massacred them. Nagumo was also able to react to attacks from Satoru Yotsumura, a powerful, former member of the Order.

**Enhanced Strength**: Nagumo has incredible raw physical strength despite his skinny build. He was easily able to lift Minimalist, a large man, by the neck with one handand stab through a car roof and someone's arm with a casual stab. He is strong enough to contend with Yotsumura's attacks which could slice through the steel supports of a car carrier trailer.

**Enhanced Durability**: Nagumo is an incredibly resilient man despite his skinny build. He remains completely unharmed after taking a powerful hit from Gaku that sent him crashing through multiple walls, a display airplane, and a car.

**Enhanced Endurance**: Nagumo was able to endure a point-blank range attack from Gaku's powerful laser that sent him crashing down from three floors above ground.

## Equipment

**Multi-Blade Weapon**: Nagumo carries a large swiss army knife-like weapon that has many different fold and pop-out blades. Although he states that it has six functions, his weapon also has two detachable short swords within it and can turn into an axe. The blades are sharp enough to pierce through a car roof and durable enough to withstand powerful blows from Yotsumura. In the past, he carried each blade separately under his trench coat.

**Dice**: Nagumo uses a dice to decide which blade he will kill his enemy by, or to distract his enemy to deliver a devastating blow.
