Issue #40 of Weekly Shonen Jump marks the 15th and final chapter of Shonen Shikku, the first major work by newcomer Tsukuda Yuuto. Since becoming eligible for fan ranking, Shonen Shikku has never managed to escape the bottom 5 of the table of contents, even placing dead last five times.

The space left by Shonen Shikku will be filled starting next week by Enigma, a new series by Sakaki Kenji, a former assistant to Amano Akira (Katekyo Hitman Reborn!). An early preview picture is available:
