Itaru Hashida

Itaru Hashida (橋田 至, Hashida Itaru), also known by his nickname Daru, his online handle DaSH ("Daru the Super Hacker") and Barrel Titor, is a main character in Steins;Gate, Steins;Gate 0 and Robotics;Notes DaSH. He is an experienced hacker and a hardcore otaku, a member of the Future Gadget Lab and a close friend of Rintaro Okabe who eventually becomes the husband of Yuki Amane and the father of Suzuha Amane. he communicates via the in-universe Twitter (Twipo) in Robotics;Notes Elite.

Appearance
Daru is a short and overweight guy who needs glasses to see.

He always wears a dark green/olive t-shirt and a pair of blue jeans along with his signature yellow cap. In one of the anime adaptation's episodes, Daru is seen wearing a yellow Hawaiian shirt.

Personality
Daru is obsessed and extremely talented with programs and computers, capable of hacking into the mainframes of top-secret organizations and processing complex computer codes.

Like Rintaro Okabe, Daru enjoys making Future Gadgets, but he is not nearly as enthusiastic about it as Okabe is. Daru also has a very particular naming sense for his creations, usually adding serial and version number even if unnecessary.

One of Itaru's most prominent characteristics is his obsession over moe culture, as well as his perverted tendencies, often to the annoyance of those around him. He describes himself as a "Perverted Gentleman". He is also a big fan of Faris.While he might not act like it, Daru is fully aware of how he comes off to other people. During his date with Yuki, he was incredibly self-conscious of being seen as little more then a fat pervert.

Steins;Gate
While Rintaro Okabe and Itaru had known one another since high school, their friendship only really began from the moment they entered university. Itaru joined the Future Gadget Lab some time after Mayuri Shiina, his reasoning for doing so being that MayQueen NyanNyan was fairly close to the lab.

While Okabe and Mayuri were off to attend Dr. Nakabachi's seminar on time travel, Itaru stayed in the lab to try to find out what the problem with the PhoneWave was, the lab's latest Future Gadget. As he experimented with it, a message from Okabe, informing him of the murder of Kurisu Makise arrived and was sent to the past through the PhoneWave, shifting the worldline towards the Alpha Attractor Field.

Alpha Attractor Field
In the Alpha Attractor Field, his phone had received an odd message from Okabe a week prior, containing only part of the message Okabe had sent to him in the Beta attractor field the same day.

Steins;Gate 0
During the events of Steins;Gate 0 in the Beta Attractor Field, Daru helped Maho Hiyajo with building a new time leap machine and often helped retrieve Amadeus' data by hacking. He also recommended Moeka Kiryu to Okabe when they needed someone who could find Kagari Shiina. He was contracted by someone anonymous, later finding out that it was Maho, to hack into Kurisu Makise's laptop.

Pandora's box
Short summary: Maho takes Okabe to the anonymous hacker she had contracted, and hence took him to Daru's secret hideout. Daru is surprised that his contractor was Maho and also at seeing Okabe. Okabe tells him that he should stop trying to hack into it. They then get a call from Amadeus [Kurisu]. Depending on if Okabe picks it up or not, the story leads into a different route.

Gehenna's Stigma
Okabe picks up the call. Amadeus tells them that someone had raided the office in Wako City and Maho's room. As they realise that this someone was after the laptop, they see several men beginning to surround the building through security cameras. Daru leads them through his secret exit and they manage to get out from the back of the building. Shocked, they escape just in time.

Presage or Recognize
Okabe does not pick up the call. Daru shows them the laptop and the hard drive. Okabe, Daru and Maho bicker and Daru advises Okabe to tell Maho about the time machine and time travelling. Okabe suggests destroying the laptop to which Daru protests that he was nearly done with it and that he would not get his pay, which he had used some of already, that way. They get interrupted by a beep from the security monitor that alerts them that multiple men have surrounded and infiltrated the building. They leave through Daru's secret exit but become cornered in an alley with Maho getting captured. At Okabe's demand the one holding Maho takes off their helmet and reveales themself to be Moeka to their shock. Okabe instructs Daru to give him the backpack containing Kurisu's laptop, which he would then give Moeka in exchange for Maho. Okabe tries stalling for time which makes the Rounders impatient and Moeka threaten to kill one of them. Suddenly, a black van pulls up at the end of the alley from which multiple armed people jump out and start shooting at the assailants. Okabe, Daru and Maho managed to duck out of the way just in time. In the gunfire the laptop is destroyed. The Rounders flee, the armed men take what remains of the laptop with them and Okabe, Daru and Maho get back to the lab, all being shaken.
