Cosmic Star Heroine game guide

The game is bugged for me in one of the story achievements. This may be one time thing or not. Contacted the developers and when I have more info will add it here.
Welcome to the Cosmic Star Heroine game guide. In this guide I will go through everything you need to do to achievement 100% completion and should take around 15 to 20 hours depending on the difficulty you choose to play in. The game is fairly linear but later in the game there are a few side quest and mission you may find your self lost and hope this step by step will help with that. So start the game up and choose hardest diffulty possible.

Chapter 1 - Planet Araenu: SkyBreaker Systems

After the cutscene here north and initite the first fight. If you are having trouble her is the solution:
* Laser
* Drown
* Breather (in the prog tab)
* Rest
* Drown
* Laser
After finishing the fights go to the menu and switch movement to run as this will make you move a lot faster and choose the difficulty you want to play the game. Keep following the path as the game is very straight forward right now and will give information when needed.

Chapter 1 or 3 - Planet Araenu: API HQ

After your first mini boss fight you will go to the API HQ, after you exit the elevator you can talk to the gaurd on the right and this will mention a soda. Now go to the cafeteria on the Southwest side and pick a soda from the middle vending machine and return it to the guard. This area has a limited access time so do this achievement as soon as you can or you will need to come back for it in a new playthrough.

Chapter 4 - Planet Araenu: Gehenna

When you reach Gehenna for the frist time you can talk to a man outside the shop on the right and this will start a quest to chase away 4 rats then talk to him without leaving area. If you leave the area just reenter and chase the 4 rats away again.

Chapter 5 - Planet Araenu: Festival

When you arrive at the festival head north and find the Rock paper Scissor booth you will have to win 7 rounds and here is the solution:
Round 1 - paper
Round 2 - rock
Round 3 - rock
Round 4 - paper
Round 5 - scissors

Round 7 - scissors
Round 8 - rock
Head north fight the cat and with Lauren now in your party use successfully use charm in this or another fight for another achievement.
