Hekiji Tengai

Tengai (天蓋) is one of the Eight Expendables who works for the Eight Precepts of Death under Overhaul.

Appearance
Tengai is a tall and thin man with short spiky hair. He wears a traditional dark colored Japanese kimono with sandals, with a long white piece of cloth acting as a belt and a white plague mask that is strapped to his face with 3 belts. A thin belt between his eyes and 2 wide belts that cover both cheeks and ears.

Personality
Tengai has a monk-like disposition, always showing calm and never losing his composure.

Tengai seems to be against excessive violence, even expressing pity on his enemies and considers enjoyment in fighting to be a low, selfish desire and as such prefers to finish his missions as fast as possible.

While talking, Tengai generally keeps his eyes closed and gives off a somewhat enlightened image, he is often seen analyzing the situation and commenting on it.

Internship Arc
During the raid of Chisaki's hideout, Tengai is paired with Rappa. When Irinaka launches Fatgum and Eijiro Kirishima into another room, Tengai and Rappa are already waiting for them. Using his ability to block Fatgum's attacks, Tengai introduces himself and Rappa as "Spear and Shield", while noting that Fatgum's and Eijiro's Quirks make him "Shield and Shield", due to their defensive natures but also points out that they can be hardly considered shields, since they cannot even defend against Rappa's punches.

Rappa tells Tengai to stop using his Quirk to shield him, to which Tengai reminds him that Overhaul paired the two up because their Quirks have great synergy together. Rappa replies by trying to attack Tengai, which he blocks with his Quirk. A confused Tengai asks Rappa what he is doing, to which Rappa replies that he does not care about Overhaul's plans and that he only wants to kill. Tengai decides to let him do as he pleases, while also reminding him to address Overhaul properly.

As Fatgum prepares to fight back, Rappa orders Tengai to not interfere, to which Tengai assures him that he will not. Upon seeing Eijiro's fear, Tengai notes that he has already given up and expresses pity for the young hero. After Rappa is done assaulting Fatgum, Tengai notices that Fatgum is preparing for another counter attack and tells Rappa to finish things quickly. As Rappa tries to finish Fatgum off, Eijiro interferes, taking his attacks and attempts a counterattack; however, Tengai blocks it with his Quirk. Tengai simply notes how meaningless it was for Eijiro to take these attacks.

Quirk and Abilities
Unnamed Quirk: Tengai's Quirk allows him to create barriers for defensive purposes. Fatgum describes that punching Tengai's barrier is like punching a steel wall.

Chisaki
Tengai is very loyal to Chisaki. He tries to follow his orders as closely and quickly as possible. Tengai also doesn't like it when Chisaki is adressed improperly.

Rappa
Tengai and Rappa do not get along very well, due to their opposite personalities. Tengai does not approve of Rappa's selfish desire to fight and how he adresses Chisaki with made up nicknames. Rappa even tries to attack him, at which point Tengai quit trying to reason with him and just lets him do what he wants.

Trivia

 * The way Tengai introduced himself and Rappa is a reference to the Irresistable Force Paradox, which is famously illustrated with a Chinese anecdote where a man sells spears that he claims are so strong that they can pierce anything and shields that he claims are so strong that they can defend against any attack. When asked what happens when someone tries to attack the shield with the spear, the merchant could not respond. However, Tengai's Quirk easily defends against Rappa's attacks.
