Touhou Kanjuden ~ Legacy of Lunatic Kingdom (東方紺珠伝 ～ Legacy of Lunatic Kingdom) is the fifteenth official installment of the Touhou Project series by Team Shanghai Alice. There are four playable characters: Reimu Hakurei, Marisa Kirisame, Sanae Kochiya, and Reisen Udongein Inaba, each with their unique shot and spellcard (otherwise known as a "bomb" in other (bullet hell) shoot-em-ups). It also features two main game modes: Legacy Mode, which functions similarly to the other Touhou games, but also Pointdevice Mode, a gameplay mode that removes lives and continues from the game but adds chapter checkpoints.
The story of the main game goes as follows: Someone is causing havoc in the Lunar Capital, and evidently, Lunarians have come to purify Gensokyo to make it suitable for them to live there (as they have a thing against what they consider "impurity"). With the help of the Ultramarine Orb Elixir (or not), the girls must now set out to stop this invasion and find the perpetrator behind this incident.
This run by kopiapoa plays the Extra Stage, which is unlocked by clearing the game on Legacy Mode without using any continues on any difficulty, as Reisen. He extensively grazes bullets in order to increase the point item value to its eventual maximum. By also milking the boss's attack patterns for score, he reaches an impressive final score of 2,429,908,660 points. For reference, the best known unassisted score is 1'016'971'530 points by kisara.
