Daisuke ARAMAKI

Aramaki is the calm minded leader of the intelligence department Public Security Section 9 (公安9課). His many connections to various politicians have helped him greatly in not only establishing the unit, but also with gathering information to deal with difficult situations.

Timeline

2027	Arise
2029	Koukaku Kidoutai (1995)
2030	Stand Alone Complex
2032	2nd GIG & Innocence
2034	Solid State Society

Alternate Universes
The anime are spread across three distinct universes.

1. Koukaku Kidoutai and Innocence
2. Stand Alone Complex, 2nd GIG and Solid State Society [Aramaki]
3. Arise [Aramaki]

The differences between the first and the other two universes should be obvious from the timeline alone. While Aramaki just started his career in Arise, only two years later he would be an old man looking at retirement. Even older than he is depicted in S.A.C. which according to the timeline comes later.

That Arise and S.A.C. take place in two different universes isn't obvious at first, but becomes clear when examining the timeline in detail. In Arise, Section 9 is formed in 2027, while in S.A.C. it is stated that the unit was established in 2029. It is also shown in S.A.C. that Motoko had the same personality during the Second Vietnam War (2015-2024) conflicting with what is seen in Arise (2027).
