Also known as "Guardian" in the US, this game is short and cheesy but fun to play for a few minutes.
Like many games that appeared in Japan first before coming to the USA, the US version is MUCH harder. Under default settings (in MAME, at least) you get only 2 life bars, as opposed to 4 in this version. You get extra lives at much quicker rate, and projectiles move slower, as well. The game would probably be best with a 3 bar setting, as 2 is a great deal harder.
I used some really cheap pacifist techniques in the last level to avoid a bunch of robo-suits that would have spawned, at the expense of a better score.
Shoutouts to ratix98 for some cool tech on defeating the level 5 (Next Future) boss. I was trying to time him out by avoiding his bullets, not even realizing you can 1-shot him with a precise strike!

Recorded with WolfMAME v .207 with default dips, INP is available on MARP if you care to see how far I got in the 2nd loop, it's much harder: http://replay.marpirc.net/r/getstarj
As with all my runs - no TAS (tool assistance), cheats, hacks or save states are used.
