Description

Touhou Koukayaku (English: Eastern Rainbow Medicine) is similar to Rockman series and features the cast of Touhou Seirensen as the bosses. Touhou Koukayaku actually is a vocal and instrumental album released by Conagusuri at Comiket 78. Later, when new album "Touhou Shinmayaku" released at Comiket 79, the game version of Touhou Koukayaku was included as an additional item. At first, you'll play as Byakuren Hijiri. but after beating the bosses you are allowed to switch characters.
Just like Conagusuri's Gensoukyou Fantasia, this game also uses tracks and includes promotional videos taken from the original album.

Plot Point: I dunno, it's Japanese so I can't read it, something to do with Nue and you must defeat her for some reason, so yeah have fun with that...... BYAKURENMAN! ALL THE WAY ACROSS JAPAN!

How it works: It's a Megaman type game, you go to stages and do your thing, except after each stage you recruit the members of the Palanquin ship, and use them to aid you in your mission to beat Nue for some reason. Yay fighting someone for an unknown reason!
 
Difference In Characters: As you unlock each character you will begin to see the differences they have between each other, the main factors to look out for are: Float time, movement speed and weapon type.

Different Sections: In each stage there are four sections (the last section is the boss battle) and every time you enter a new section, your health is refilled, so no having to look for cheese (the health restoration items) before you move on.

UFOs: In order to fight the boss rush you must collect UFOs in each stage, you can find the location of said UFOs by getting Nazrin and looking around in each stage until Nazrin gets a blue circle on her. How do you get the UFOs when this happens? Well, you go look around the area where Nazrin is all "Oh man, a UFO is around here." (Normally left or up of where the indicator goes off) and turn into Shou to reach the areas with the UFOs. Once you have collected them all, the question mark stage will now be available to enter (the picture will show all of the bosses now that you have all of the UFOs) and good times will be had if you loved fighting the bosses of the game.
