Source-derived summary

The Knight in the Area (Japanese: エリアの騎士, Hepburn: Eria no Kishi) is a Japanese manga series written by Hiroaki Igano and illustrated by Kaya Tsukiyama. It was serialized in Kodansha's shōnen manga magazine Weekly Shōnen Magazine from April 2006 to March 2017, with its chapters collected in 57 tankōbon volumes. A 37-episode anime television series adaptation produced by Shin-Ei Animation was broadcast on TV Asahi from January to September 2012.

Plot

Kakeru Aizawa is the younger brother to Suguru Aizawa, a soccer prodigy belonging to Japan's under-15 national team. Prior to the series, Kakeru quits his position as a forward after a traumatic experience prevented him from playing with his left leg and settles for a managerial position. After the two are hit by a truck, Suguru dies and has his heart transplanted into Kakeru. With it, Kakeru returns to soccer to achieve his brother's dream of winning the World Cup.

Voiced by: Yūko Sanpei

Kakeru is Suguru's younger brother and a forward on his soccer team. After accidentally injuring his teammate Hibino with a powerful left-footed shot in sixth grade, he avoids using that foot, severely limiting his scoring ability and confidence. He gradually withdraws from playing, assisting as manager instead, frustrating Suguru.

Editorial analysis

Why this record matters

The phrase “japanese manga series” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 24, 2026. The linked authority identifier is Q1189409. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2006, 2017 and 2012.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
