Why didn't Gai Kureinai accept the invitation of the Otto brothers to stay in the country of light?

In Altman, the country of light, as the biggest star of Otto at present, lives on this planet with powerful Otto warriors such as the father of Otto, Otto brothers and so on. In the Showa period, Altman would be very proud if he could become a member of the country of light. In spite of this, not all Altman are willing to join the country of light nowadays. Facing your question here, I think Gai Kureinai's unwillingness to stay in the country of light is mainly related to his long-term experience and management in the country of light. Here is the reason, and then I will give you a detailed answer.

Oberman, who appeared in the Cenozoic era, is different from Altman in the Showa period in personality, setting and so on. Oberman himself does not belong to the country of light. Although he was trained by Saiwen and Ciro, his strength has been greatly improved, but this cannot be a deal for him to stay in the Valley of Light. However, this is also the reason why he is unwilling to accept the invitation of the Otto brothers to stay in the country of light.

As far as Oberman himself is concerned, the real origin is not clear at present, but as far as the character he shows in the plot is concerned, as a "Lang Ke", he doesn't want to stay in any enemy for a long time. For Gai Kureinai, constant wandering is his life. Since Gai Kureinai has this idea, in the face of the retention of the Otto brothers, once he really stays in the country of light, he will lose his freedom. For this reason, Gai Kureinai naturally won't want to stay in the country of light.

In the country of light, since the establishment of the Cosmic Guard, there has been a pyramid management system in the country of light. As a figure at the top of the pyramid, King Otto is the biggest leader in the country of light, but because King Otto has lived on the star of the king for a long time, the country of light has always been led by the father of Otto. In the face of such a management system, it is absolutely impossible for a long-term unrestrained Aubrey Altman to stay and restrict his freedom by himself.
