I checked the current length of the story, if anybody's curious about it, calculated based on total words in dialogue blocks (narration and character dialogue):
- Total word count as of now: 217,627 words
As for which characters have had the most dialogue, based on dialogue blocks:
- Mary has 8,491 blocks if dialogue
- Kendo has 6,958 blocks of dialogue
- Satoshi has 2,473 blocks of dialogue... but there are 4,424 narration blocks, and most of them belong to him
They are all followed by Erina and Natsuki, who have around 1,700 each, and Hanako, who has 1,100 (she is a quiet girl).
Surprisingly, Yoshi stands at around 700 dialogue blocks, above Shizuka and Rin who both have around 600 (but this is due to their late arrival to the story). I suspect Arato will overtake him soon enough.
And finally... Dude 1 and Dude 2 both have 23 lines of dialogue each.
