Traveling is a way to meet people and make new friends. Sometimes it takes a while, but never forget to enjoy the ride.
Holy Night is full of ruthless final bosses. Bigger, stronger, faster, and more brutal than you. And you're just human, but you have your weapons, combat skills, and your sense of humor.
The latter might not be very useful, but it makes the nightmare you're about to face a little more bearable.
Always be positive. After all, the purpose of a good final boss is to test your strengths and weaknesses to become a better person.
