Enishi had been planning his revenge for ten long years.
The forest was the best place to welcome his old friend the battousai. He wanted him to suffer and make remember the terrible day his Nee-San was savagely assassinated.
On that day Kenshin had had to face all sorts of opponents, whom he defeated one by one before he reached the old wooden barrack where his sister was waiting for him.
But Enishi had no intention to resolve to other men to beat his life enemy.
Even if the battousai manages to pass all the traps he set in the forest he would be weakened and would finish him off the way he should have been finished off ten years ago.
He had carefully placed every trap at various distances from each other. Some were explosives. He thought that - if the battousai would escape the explosives - which could be, as Kenshin could recognize the smell of gunpowder - they would at least blind him.
Some of the traps were knives that were carefully placed so to hurt him without killing him.
His wicked mind had no limit.
