Long-time fans have also expressed emotional sentiments, like "Spitz was always what I listened to during my school days. It's truly wonderful to still be able to hear their new songs 30 years later and to love them," highlighting the band's enduring popularity and affection from many over the years. Furthermore, theories are circulating that the lyrics and song deeply resonate with the anime's worldview, with interpretations like "protecting what's cute" and "the image of someone strongly pulling a hand joined to survive a difficult era."

Even the title "Tomo o Mamoru" itself has sparked deep interpretations regarding its reading and embedded meaning, such as "The undying lamp of dharma? Be a lamp unto yourselves, be a refuge unto yourselves!" and immediate expectations like "Undoubtedly a premonition of a masterpiece." Many fans are eagerly awaiting the broadcast on October 4, curious to see how the new "light" spun by Spitz will illuminate the story of 'SPY×FAMILY.'
