The future I want to protect

This ballad is told from the perspective of a teenage boy who was forced to lose his life as a kamikaze pilot during the final stages of the Pacific War.
Key points of the video:
Historical context: It depicts the harsh conditions faced by young men who were sent on kamikaze missions by national order as the war situation worsened.
Theme: It encompasses the fear of being branded as an "unpatriotic citizen" and the internal conflict of young people at the time who were forced to make the ultimate choice of their own death.
Message: It expresses a wish for peace, hoping that the lives lost as kamikaze pilots will be reunited with their families and loved ones in reincarnation and that they will finally find happiness.
A poignant yet heartwarming story unfolds with animated visuals, suggesting that "the important people around us may have already met in a past life."
Self-sacrifice to protect loved ones: As the lyrics (0:35-0:40) indicate, the greatest motivation is personal affection—"for the sake of protecting someone important, even at the cost of one's own life." This is a choice to prioritize the future of loved ones—family, friends, and partners—over one's own future.
Liberation from the stigma of being an "unpatriotic citizen": According to the video description, in the harsh social context of the time, participating in suicide attacks also suggests an aspect of avoiding the stigma of surviving. It reflects the agonizing decision faced by young people at the time, a desperate attempt to protect their dignity and the safety of their families through death.
Connecting to hope for the future: The desire for "reunion" (from the video description)—that their souls would be reborn after their lives ended and that they would meet their loved ones again and find happiness—is the ultimate solace and driving force behind their actions.
The "ultimate resolve" sung about in this song is a spirit of self-sacrifice, the willingness to even sacrifice one's own life to protect loved ones.
The background information gleaned from the lyrics and video description is as follows:
Those to Protect: Prioritizing the future of irreplaceable family, friends, and loved ones above all else (0:35-0:40).
The Ultimate Choice: As a kamikaze pilot at the end of the Pacific War, he is in a situation where he cannot return alive. However, the song depicts his resolve to choose "protecting the future of his loved ones" over the stigma of being labeled an unpatriotic citizen and the fear that comes with it.
A Wish for the Future: His heartbreaking yet resilient resolve is that even at the cost of his own life, he would be content if his loved ones could live a happy future (0:49).
In the context of the video, this is not simply an acceptance of death, but rather a loving determination that believes in the connection of souls, expressing the wish that "even after death, they will reunite and be happy in the next life."
The "light" (0:55) mentioned in the lyrics of this song is not merely physical brightness, but is thought to symbolize "the fading life and, in contrast, the continuing hope and future."
