Subaru Natsuki

Natsuki Subaru is the main protagonist of the Re:Zero kara Hajimeru Isekai Seikatsu anime and light novels.

Subaru is a shut-in NEET who is sent to a fantasy world. He officially becomes Emilia's knight following the incident at the Sanctuary and later revealed to have the necessary qualities to become a Sage candidate.

In the Heroes Coalition fics, Subaru is part of the Heroes Coalitions as a trainee. She also attends the Vanguard Academy.

Appearance
Subaru has short black hair and brown eyes. He is described to have an ordinary look and an evil gaze due to his sanpakugan. He usually wears the tracksuit that he was wearing when he was summoned but other outfits have included the butler's clothes he wore when serving at the Roswaal mansion.

Personality
While Subaru tends to not read the situations he encounters, ultimately leading him to make irrational decisions, he is loyal to those he holds dear, willing to help them, even if that means taking the thorny path. He has his resolve confirmed through the many situations and circumstances he faces in the fantasy world, originally having been one to always take the 'easy' route. As a shut-in NEET, he is hopeful of the possibilities that being sucked into a new realm brings, but later realizes the realities of the predicament he is in. Eventually, he resolves himself to be faithful and protective of the ones that he cares most about.

Currently, Subaru has lost any of his memories from the moment he came to the other world.

Abilities
Return by Death (Shinimodori): Returns the user to a "save point" after death. This ability was given to him by Satella as a means to help him save the ones he loves should he need it.

Authority (Ken'nō): Subaru is currently able to use two Authorities, Sloth and Greed. His Return by Death is also rumored to be an Authority but nothing has been confirmed. Magic User: Subaru was formerly able to use Yin Magic before his gate collapsed, though he is still able to use it to a certain extent with Beatrice's help by using her as a gate instead. He later comes up with three Yin Magic that he is only able to use with Beatrice. Of the three magic, the third one is still incomplete, and each magic can only be used once per day. Spirit Affinity: Subaru has a rare innate gift to form contracts with spirits.
 * Authority of Sloth (Taida no Ken'nō): Subaru gained the ability to use the Authority of Sloth after Petelgeuse Romanee-Conti's death.
 * Unseen Hand (Miezaru Te): The user can cause physical interference by creating an invisible force field in the shape of a hand. Subaru later renames this technique as Invisible Providence (Inbijiburu Purovidensu), though he is only able to control one hand and its range is minimal.
 * Authority of Greed (Gōyoku no Ken'nō): Received after the defeat of Regulus Corneas in which Subaru became it's current holder.
 * Cor Leonis: Alternatively known as "Lion Heart". An reverse positive form of "Small King" which Subaru gained in Arc 6. As such it works inversely to how Small King does in which Subaru takes on the burdens of others, be it physical or mental by transferring them to himself temporary in-exchange for increases in their combat abilities. It only works on people Subaru has a emotional connection to whom he can sense by seeing them points of lights when the authority is active. It can be used to derive the relative positions of everyone and their emotional states to himself.
 * Shamak (Shamaku): Shamak enables Subaru to trap his opponent in a area of darkness that confuses their senses. As it was the only magic he could use before his gate collapsed, he used it a number of times, and even came to grow attached to it, calling it "Shamak-san".

Spirit User (Seirei Tsukai): Subaru is contracted with the Artificial Spirit Beatrice, though according to her he isn't a true Spirit User. She also has a terrible mana consumption rate and formerly got around this by draining mana from people in the mansion using the library as a medium. Like Julius, Subaru is also considered be a Spirit Knight (Seirei Kishi). As she is an Artificial Spirit, she also has several conditions Subaru is forced to follow: Spirit Arts: Following Arc 4 Subaru is able to use this. Melee Fighter: While he is not a skilled warrior like Reinhard and his other companions, he is shown to have a basic grasp of melee combat and was able to briefly hold his own against Elsa, as well as shown by his aptitude in dodging Felt's swings when confused for an intruder. He also demonstrates strength in holding back the thugs that assailed him.
 * Subaru cannot form a contract with other Spirits
 * Beatrice cannot restore mana on her own
 * Beatrice cannot use the mana in the atmosphere
 * Beatrice can only drain mana from Subaru
 * E・M・M (Emiria-tan Maji Megami, "Emilia-tan is Seriously a Goddess"): E・M・M is an "absolute defense magic". Beatrice uses Yin Magic to interfere with the time and space around Subaru, and while he can't move during activation, he experiences no interference from outside the barrier. It is similar to the Authority of Greed but doesn't have the same risk, and can be used until mana runs out.
 * E・M・T (Emiria-tan Maji Tenshi, "Emilia-tan is Seriously an Angel"): E・M・T is an "absolute negation magic". A spherical field several ten meters long with Subaru and Beatrice at the center is created which negates effects from mana within it. Julius remarks that it is useful against mages and those who use mana to assist their techniques. However, the magic only negates the use of mana, and so it has no effect against opponents who fight without it.

Parkour: During the several months after the incident at the Sanctuary, Subaru learns the basics of parkour from Clindand begins training himself.

Equipment: Subaru uses a whip as his main weapon. Like his Parkour, Subaru learned the basics of using it from Clind. In the Light Novel, it was revealed that the whip is made of the Demon Beast they fought in Arc 4, the Jet Black King of the Forest Guiltylowe.

Patrasche (Patorasshu): Patrasche is Subaru's black Earth Dragon that he officially received from Crusch for his efforts in the Hakugei battle. It is female and of the Diana species. Despite being of a species known for being feisty, Patrasche is extremely loyal to him, as she is willing to put her life on the line to serve him.

Defective Gate: After the events of the Sanctuary Subaru completely ruptures his "gate" due to over-stressing it by casting magic while it was still recovering from demon beast incident in Arc 2. Now he can no longer use magic on his own at all becasue he cannot expel the mana which puts him at risk of dying from "Mana Poisoning", a state when too mana builds up in one's Od due poor mana circulation. Fortunately his now permanent contract with Beatrice allows her to absorb the excess mana via physical contact which they do daily.
