Slam Dunk, Vol. 20 continues where the previous tankōbon left off and contains the next nine chapters (171–179) of the on-going manga series.
The tankōbon continues the game of Shohoku High School and Ryonan High School. With Ryota Miyagi scoring, Shohoku continues to lead by almost fifteen points. As such, Coach Moichi Taoka of the Ryonan team is forced to make Jun Uozumi return to the game. Uozumi manages to reduce Ryonan's disadvantage with help from Akira Sendoh, and continues rebounding most of Shohoku's missed shots.
The high performances from Uozumi and Sendoh allow them to reduce Shohoku's lead to only ten points. Sendoh continues to contain both Kaede Rukawa and Hanamichi Sakuragi, and Ryota Miyagi has problems defending and commits fouls. Rukawa and Sendoh continue scoring making, alternately expanding and reducing Shohoku's advantage. However, with only two minutes left, Sendoh reduces the gap to only two points and Hisashi Mitsui suddenly falls unconscious.
This tankōbon is written and illustrated by Takehiko Inoue. For the most part, the game between Shohoku High School and Ryonan High School was narrated and depicted rather well. It is rather getting a tad ridiculous as this tankōbon literally spans six minutes of the game. The dramatic cliffhanger with Hisashi Mitsui falling unconscious makes the chances of Shohoku High's advantage of two points in a precarious position as the Nationals are on the line.
All in all, Slam Dunk, Vol. 20 is a wonderful continuation to a series that seems intriguing and I cannot wait to read more.
