Grapple

Grapple (グラップル) is an IT company.

Principles
One of Grapple's products is a brand of smartphone called the MilliPhone (ミリフォン). There are several models of MilliPhone, such as the MilliPhone 15 High End. MilliPhones are rumored to have an obsolence system called Telomere. Grapple also sells a smartwatch which functions in conjunction with the MilliPhone.

At least some of Grapple's products, include MilliPhones and tablets, have voice-command functions and run an AI known as Seri (セリ).

Grapple's logo is an apple with lines and a stem in the shape of a stylized 'g', sometimes used on its own.

Background
At some point in the recent past, when Aradia had an old lady perish in her hands as a result of modern-day witch persecution, a nearby billboard was advertising the autumn release of Grapple's MilliPhone 15 High End.

Christmas Day Arc
Although not specifically identified as a Grapple product, Aogami Pierce's notebook-sized tablet, seen during his hospital stay on December 25th, ran the AI Seri on it.

Los Angeles Arc
Harvas Spring had a MilliPhone, which his daughter apparently loved more than him, and was using it when he travelled to Los Angeles before getting caught up in the mass disappearance. His daughter would later request one of her one when his wife Monoetta Spring headed out for LA.

Melzabeth Grocery made use of a reduced-spec MilliPhone and associated smartwatch, which were found by Kamijou Touma and had clues which he used to follow her trail, finding her daughter Helcalia Grocery in the process. Her use of a rival company's products over an R&C Occultics model indicated her distrust of the company to Touma, a fact he used in his efforts to convince Helcalia of her mother's innocence.

A Grapple shop full of MilliPhones in LA would also be struck by one of Citrinitas's attacks on Touma's group, prompting a remark from Touma. The company was also briefly mentioned in the White House with regards to an amendment to the Patriot Act forbidding phones in a debate.

New Year's Eve Arc
During Kamijou Touma's work in Shibuya on December 31st, a billboard in the background was advertising a Grapple product.
