Diligent and methodical honor student Eiichirou Maruo decides to exercise more during the little free time he has available because he is worried about his health. For this reason, after seeing a flyer, he joins the Southern Tennis Club at the beginning of his freshman year. During his free trial at the club, he meets Natsu Takasaki, another first year student, who is determined on becoming a professional tennis player due to her love for the sport. In contrast, Eiichirou's study-oriented life exists because he believes that it is what he has to do, not because he enjoys it. However, his monotonous days come to an end as the more he plays tennis, the more he becomes fascinated by it. Baby Steps is the story of a boy who makes the most of his hard-working and perfectionist nature to develop his own unique playing style. Little by little, Eiichirou's skills begin to improve, and he hopes to stand on equal footing with tennis' best players. [Written by MAL Rewrite]

Inspectors Arata Shindou and Mikhail Kei Ignatov have uncovered a dangerous conspiracy. The Sybil System, the ultimate judge of human character in Japan, is being undermined by a criminal syndicate that is amassing wealth and power in the shadows. Now, Bifrost agent Kouichi Azusawa launches a direct assault upon the Criminal Investigation Department by occupying its headquarters and taking Inspector Shindou and everyone with him hostage. CID Unit 1 supervisor, along with Chief Mika Shimotsuki and former unit members Shinya Kougami and Nobuchika Ginoza, face the task of reclaiming the building and saving everyone inside. Alongside the hostage situation and Azusawa’s demands for Tokyo governor Karina Komiya’s resignation, there is a sinister plot hatching in the background—a secret plan that will force Inspector Shindou to confront not only Azusawa but also his own past. These events slowly bring him closer to unshrouding the mystery that has eluded him and his best friend, Ignatov, for many years. [Written by MAL Rewrite]
