Ebisu, Shibuya in 1992. In April 1991, Square merged with an identically-named dormant company in order to change its share prices. As a result of the merger, Square's foundation was backdated to the other company's July 1966 founding date. At that time, Square drew some of its development funding from loans from Shikoku Bank. Due to the increasing costs of development, the bank sent Tomoyuki Takechi on secondment to be their office manager in 1990. Takechi's secondment lasted until 1994, by which time Square had annual sales worth ¥16 million per year, and he had become inspired by Sakaguchi's vision for the company. In August of that year, Square registered with the Japan Securities Dealers Association to offer shares for public purchase. Sakaguchi was by now a prominent figure within the company, and was promoted to Executive President in 1991. His increasing corporate involvement lessened his creative input, prompting him to give greater influence to director Yoshinori Kitase. Gebelli left Square in 1993, retiring on royalties from the Final Fantasy series. Miyamoto stepped down as Square's President in 1991 while remaining a major shareholder, and was replaced by Tetsuo Mizuno. In 1991, Suzuki became Vice President. Besides Final Fantasy, other projects were produced which spawned their own series. Kawazu helmed an RPG project for the Game Boy. Released in 1989, Makai Toushi SaGa (The Final Fantasy Legend) spawned the SaGa series, which Kawazu would continue to be involved over the years. After the release of Final Fantasy III (1990), Ishii was offered the chance to create his own game, leading to the production of Seiken Densetsu: Final Fantasy Gaiden (Final Fantasy Adventure) for the Game Boy in 1991. Ishii went on to develop additional Seiken Densetsu titles, released outside of Japan as the Mana series. A lesser-known series was the Japan-exclusive real-time strategy series Hanjuku Hero, which began in 1988 and focused on parodying conventions of the RPG genre. The company also developed several notable standalone titles including Chrono Trigger, born from a collaboration between Sakaguchi, Dragon Quest creator Yuji Horii, and Dragon Ball artist Akira Toriyama; Super Mario RPG, produced in collaboration with Nintendo using characters from the Mario franchise; and the Western-exclusive Secret of Evermore. Speaking in 2001, Sakaguchi noted that while Final Fantasy was the company's most recognized property, Square's cultivation of several other series meant that it did not have to rely on Final Fantasy to
