In the episode 13 of Ultraman Teliga, Captain Tatsumi "disappears", led by Ma Lulu, causing an interesting oolong incident. Although it is a routine reminiscence, the play also reveals a lot of hard work. For example, the mystery of the birth of the true sword enlightenment, why he would be "the sword enlightenment is Treka".
In the Dark Triga incident between them, sword goggles to 30 million years ago, physically touching dark Triga, and also learning his true identity "Sword Goku is Trija, Trija is Sword Goku". This sentence is actually quite puzzling, why is the sword enlightenment the Trega itself?
In episode 13, Kengo tells him the truth about Shōjo and Yumei, and also solves the mystery of the birth of Kengo. The Sword Enlightenment was born from the light of the Triga, who was the Terriga himself who awakened 30 million years later. Kengo also talked about his mother, and perhaps knew about it, so he always gave Kengo a sense of mission.
How to understand that the sword enlightenment was born from the light of Triga? There are two assumptions.
The first is the "Relic Child of Light" that has been circulating on the Internet. Here's the thing, 20 years ago, Sword Goku's mother discovered the pyramid ruins of Triga, and then found a glowing baby in the ruins, the baby was born from the light of Triga and grew up to be Sword Goku.
The second is rebirth or rebirth. The Sword Enlightenment is derived from the Light of Triga and was born through human conception. The explanation is that the light part of Trega is conceived and reborn by the mother of the sword. Such an event led to a special child, that is, the legendary "both light and human beings".
Regarding the birth of the sword, I don't know whether the second half will be made public, or whether it will be explained in such a sentence, I don't know. But the sword enlightenment does seem to be Trega himself.
