Itaru Hashida

Itaru Hashida (橋田至, Hashida Itaru), also known as Barrel Titor in 2025, is an experienced hacker in both software and hardware technologies. He is also well-versed in things pertaining to otaku culture. Rintarou and Mayuri call him by the nickname "Daru".

He is Lab Member 003.Already joined since episode 1.

Appearance
Daru is obviously overweight, something few characters have taken notice of during the course of the story and later becoming a significant plot point. He is apparently taller than Rintarou.

Daru 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 episodes Daru is seen wearing a yellow Hawaiian shirt.

Personality
Daru is obsessed and extremely talented with programs and computers, capable of hacking into top-secret organizations's mainframes and processing complex computer codes. He is very proficient with the IBN5100, though is unable to make out any of the information he dug up due to his lack of skill in English.

Daru, like Rintarou, enjoys making Future Gadgets, but is not as enthusiastic and has voiced his desire to sell them for money briefly in the visual novel. Daru is apparently bad when it comes to naming, as he would always add an irrelevant model serial and version number to the end of the gadget's name.

He supposedly has an obsession with both 2D and 3D girls and is a big fan of Faris. Because of his speech, he is called and known as a major pervert. Daru supposedly possesses rich knowledge when it comes to dating, as he gave Rintarou "advices" on his upcoming date with Ruka, though Rintarou claimed that Daru was just using experience from his H-games, and does not have any real "skills".

History & Plot
He and Rintarou have apparently known each other for more than two years, though Daru himself claimed their friendship has only been a year old. Itaru doesn't mind when he is called "Super Hacker" but doesn't like it when people mispell it as "Hakah", a common mispronunciation that Rintarou uses most of the time.

Like Rintarou, he is a first year at Tokyo Denki University. It is later revealed in the series that he is the father of Suzuha. In the Alpha world line, he and Rintaro became founders of the Valkyrie, a resistance against SERN and the Illuminati. He met his wife, Yuki Amane, a famous cosplayer, in the 2011 Winter Comiket after escaping from the SERN headquarters. After Rintarou was murdered in 2025, he continued research on the time machine and invented one for Suzuha to use in 2036. However, this machine was incomplete and could only travel backwards through time, as Daru was killed by SERN in 2033 before completing the machine.

After Suzuha succesfully retrieves the IBN5100 in 1975, she arranges so that Daru and Rintarou receives it. Daru in 2033, knowing about his death and the flaw of the time machine, finished it before time so that Suzuha can use it to travel back and forth in time. With the prevention of SERN's acquisition of Kurisu's research, the future does not become a dystopia and thus, does not neccesitate the invention of Daru's time machine.
