Bad Ending

You can't clear Hiroya's route if your affection level is too low. You can't also clear the game when Kazuha's (or your) Almighty Level is too low.

Merry Bad Ending

To get Hiroya's Merry Bad Ending, you need to satisfy the following condition:

Kazuha (or 'you') Almighty level to max (5 out of 5) AND;
Hiroya's Affection level to 0 out of 10.

You can get this Merry Bad Ending by:

Going to Quest Seven of Hiroya's route:

Title Screen > History > Hiroya's Route > Chapter/Quest Seven > Select Kazuha's Affection Level to Max > Select Hiroya's Affection Level to 0.
Select 'Repeat this Chapter.'
Select the answer: "How about Radius?" > "Don't lose to my brother."
