>>93001886Your long journey is finally reaching its end, it's time to face the Great Demon King. When it's time for you to deliver the killing blow, you manage to spit out only few pathetic sparks out of your magic staff. The rest of your party turn towards you and see a shivering spiritless man and ask you what's wrong in panic.
The previous day you happened to meet a succubus (Marine) and you spent all your mana to have the most mindblowing sex marathon in the history of the universe with her. This part is over 95% of the story.
The story returns to the following day and you briefly summarize everything and say "I guess I didn't manage to recover my strength in time, heh." Your party members curse your name before they all get wiped out by the Great Demon King, you just reminisce the great time you had last night before it's your turn to get rekt.
