In the far future, mankind has successfully expanded to the far reaches of the solar system. Six planets have been previously explored in the past and people had already emigrated there. Beyond the sixth planet lies a seventh Earth-like planet, Seven Tier. Seven Tier was considered a suitable planet for humans to live, and in the process, the planet also had a large amount of energy called "Septonium". The energy company called the "Magnificence Energy Corporation", or the Magni company, turned its eyes toward the Septonium. Soon after, Magni was successful in terraforming the planet, and people began to immigrate to the planet. A space police agency dubbed "Mitsurugi Security Service", or MSS for short, was formed for the sole purpose of protecting Seven Tier and its people. Alex Heatburn and his partner Margaret Whitetail are both pilots for the organization, flying the FV-G27 Enforcer in their missions under the callsign "Hound 1".

Alex: With Viridian's plot put to an end, the people of Seventh Tier were saved. His plans would later become evident to the people, Specia returned to her monitoring duties, and peace was restored to Seventh Tier. Seventh Tier had been developed for the express purpose of harnessing septonium energy, and the planet could now only wait to see what the future held. Nina and Captain Brown were released safely, and, once more, in all of the confusion, Seram and Fuam were apparently able to make it out as well. Resourceful, those two! Tini's genius in handling the situation was recognized, and she decided to become an engineer. ...Though she would be strictly monitored by Specia. And though Margaret and I are still working together, that's a story for another day. Well, see ya later!

Nina: With Viridian's plot put to an end, the people of Seventh Tier were saved. His plans would later become evident to the people, Specia returned to her monitoring duties, and peace was restored to Seventh Tier. Seventh Tier had been developed for the express purpose of harnessing septonium energy, and the planet could now only wait to see what the future held. Captain Brown and myself were released without incident. Alex and Margaret do not speak much of the events which recently transpired, but the two of them are no doubt heroes of all of Seventh Tier. Though I plan on continuing down this path, that's a story for another day. Well then, until the day we meet again!
- On Hard, the ending is narrated by Nina.
- Nintendo Hard: It is a Bullet Hell game, after all. The hardest difficulty, on the other hand, gives us even more bullets that are much harder to dodge and you must inflict more damage on the enemies and bosses.
- Oddly Small Organization: MSS seems to be such. Being a security company you'd expect them to have a little more members, but the only ones shown are Alex, Margaret, Brown, and Nina.

IT'S ALL YOUR FAULT! YOU'VE DESTROYED MY PLANS!!! I'll send all of you... ALL of you straight to hell!
- What Happened to the Mouse?: What happened to some of the characters after the events of the game is unclear. In the case of Natsuki, it was unknown what happened to her following her boss battle, but Natsuki Chronicles finally gives an explanation. In the case of Jack, it was at least mentioned in passing that he was to be apprehended by another group.
- Why Did It Have to Be Snakes?: Margaret seems to have a fear of spiders, as the small mechs that have hijacked the shuttle in Chapter 6 are in the form of spiders.
