This chapter is the start of a new arc. A new Demon Sword will be born in the world, and Kakeru gets a lot more harem members and also wins a lot of things. Well, if you read the story until now, you should probably had guessed that. Only 4 chapters to until I exceed the other translation.
If you haven’t read this because it already had been translated before or interested on the series, you should start now. You might have forgotten what happened in the past, or different name spelling and stuff, so I suggest you re-read it.
Here‘s Chapter 31 of Lottery Grand Prize.
