Mitsuru Adachi (あだち充 in Japanese) is a Japanese manga artist. After graduating from Gunma Prefectural Maebashi Commercial High School in 1969, Adachi worked as an assistant for Isami Ishii. He made his manga debut in 1970 with Kieta Bakuon, based on a manga originally created by Satoru Ozawa. Kieta was published in Deluxe Shōnen Sunday (a manga magazine published by Shogakukan).
Adachi is well known for romantic comedy and sports manga (especially baseball) such as Touch, H2, Slow Step, and Miyuki. He has been described as a writer of "delightful dialogue", a genius at portraying everyday life, "the greatest pure storyteller", and "a master manga artist". He is one of the few manga artists to write for shōnen, shōjo, and seinen manga magazines, and be popular in all three.
His works have been carried in manga magazines such as Weekly Shōnen Sunday, Ciao, Shōjo Comic, Big Comic, and Petit Comic, and most of his works are published through Shogakukan and Gakken. He was one of the flagship authors in the new Monthly Shōnen Sunday magazine which began publication in June 2009. Only two short story collections, Short Program and Short Program 2 (both through Viz Media), have been released in North America, though Viz is scheduled to begin publishing Cross Game in October 2010.
He modeled the spelling of あだち (rather than 安達) for his family name after the example of his older brother, manga artist Tsutomu Adachi. In addition, it has been suggested that the accurate portrayal of sibling rivalry in Touch may come from Adachi's experiences while growing up with his older brother. Adachi did the character designs for the OVA anime series Nozomi Witches, so he is sometimes incorrectly given credit for creating the original series.
Piano piano facciamo dei passi avanti e i protagonisti prendono sempre più coscienza dei loro sentimenti - anche perché ormai è più che evidente che Keisuke è destinato a confrontarsi con Hiroki Nakanishi, non solo per diventare il nuovo campione nazionale dei 100 m stile libero, ma anche per conquistare il cuore di Ami, divisa tra il legame di lunga data con il suo "fratellino" e il crescente affetto per quello che un tempo aveva bollato come "l'odiato Yamato". In questo volume fa la sua comparsa anche il padre di quest'ultimo, decisamente meno fissato con la storia della rivalità degli Ninomiya e che non sarebbe nemmeno troppo contrario a un'unione tra Keisuke e Ami. Qui a tenere banco è il torneo delle scuole superiori, ultimo banco di prova prima dei nazionali - prova che il nostro protagonista supera alla grande, ma il plot twist finale ci priva del tanto atteso confronto con il suo idolo Nakinishi e lascia presagire nuove difficoltà nel rapporto con Ami.
