- Anvilicious: With works of this didactic nature, it's hard not to be. Especially when the story revisits some concepts explored in previous chapters. It's difficult to ignore when the English publication jams two volumes into one.
- Funny Moments: For such a melodramatic series, there are a few moments that stand out, but the Kaleidoscope Incident (where Sachiko finds herself scrambling to keep Hikaru from hurting himself or Kanon with the glass bits inside of the toy, while everyone keeps giving Hikaru more kaleidoscopes) tops them all.
- Germans Love David Hasselhoff: "With The Light" manga seems to be exceptionally popular among American fans due to the "Autism and Special Needs" theme throughout the series.
- Ho Yay: Happens a lot in Volume 3 (Volumes 5 & 6 in Japan). Nobuaki blushes when he leans on Hikaru's desk, saying "I hope he can stay forever!" Kanata lays on a P.E mat next to Hikaru, and they just kinda nudge each other. And for a class play, Kanata plays a female role. Very well. Also a Toy Ship.
- Jerkass Woobie:
- This may be a bit of a stretch here, but Masato's mother definitely qualifies. Even though she frequently berates Sachiko and Hikaru on a regular basis and favors Kanon, even she had her own problems (like not being congratulated when she gave birth to a girl, as her family really wanted a son).
- Oki and the kid who bullied him in the orphanage also apply.
- Mrs. Katakura also qualifies. She and Sachiko fell out after she'd once badmouthed Hikaru behind Sachiko's back, then later indirectly put the boy in danger twice: once by deliberately giving Sachiko the wrong time for the school students to meet up, and when Sachiko confronted her on it, acted callous and indifferent; and later through her eavesdropping daughter Eri, who chose not to inform the teachers that Hikaru was in a locked shed where he suffered an accident. However, Katakura's attitude toward Sachiko stems largely from jealousy that Sachiko appears to have a better life than her despite caring for a disabled child; we're soon shown that Katakura's (older) husband is abusive, chauvinistic, and disaffectionate toward her, and had refused to let her return to work after she had Eri.note After confessing to Wakabayashi-sensei of the state of her home life, she breaks down in tears once she returns home, scared of her husband, and thinking no one loves her.
- Moe: Hikaru Azuma definitely has his own way of being cute, Even Kanon.
- Nightmare Fuel:
"It's all your fault!"
- Sachiko's mother-in-law blaming the poor mother for Hikaru's outburst in the funeral, complete with a shot of her raw hate.
- The bullies robbing Hikaru on his way home, taking away his GPS while Hikaru panics. Not easy to watch for victims of bullies, especially autistic victims.
- Some Anvils Need to Be Dropped: Even in this day and age, the amount of ignorance and misinformation concerning Autism is surprising. It's very hard for autistics to be properly accommodated in many places, and their treatment in Japan (Asia in general, actually) is even worse.
- Sweet Dreams Fuel: For all of the struggles that Sachiko and her family go through, you can't help but just feel as happy as they do when things go right for them. Hikaru and Kanon are just adorable, too.
- Tear Jerker: Has its own page here.
- Values Dissonance: A deliberate example. Similarly to the manga A Silent Voice, In early volumes, when Hikaru's autism manifests and he occasionally causes trouble, many people are quick to blame the parents for his misbehavior, claiming that they don't discipline him properly or say to their faces that they should lock him up. Sometimes people have claimed Hikaru is a straight-up bad kid. Plus, at one point, late in the series, Hikaru's grandmother tries to keep Hikaru in the house in an attempt to hide him from others, thinking him to be a burden and an inconvenience, and as such, she and Sachiko clash over their ways of treating Hikaru. This is because the Japanese still have a rather skewed view of mental illness, under the belief that the mentally ill person isn't actually ill, but that their problems are personality/character flaws or just plain being an asshole, and that their problems can be fixed if they stop whining and change themselves so they can better meet society's standards. With Japan being a rather conformist society, any deviance from their rigid social norms is considered unacceptable, with many not being very understanding of how autism, or mental illnesses in general, really works. To be fair, the manga does expect the audience to side with Sachiko and her family, and many people who at first dislike Hikaru and don't understand autism do become a bit more understanding—with some exceptions—but it's a good look into a side of Japan that people rarely get to see.
- Values Resonance: With subject matter like this, you'd think it was made just recently. But nope! This was written in 1999, years after autism finally got to be recognized as a neurological disorder. Not only does it treat its subject well, it also addresses (and berates) common Japanese stereotypes related to autism, such as the Japanese's words' meaning.note This manga's messages become more and more relevant with each passing year, especially now that the majority of people on the autistic spectrum are becoming adults who may very well need support in a world that feels they either need to be fixed or that they're incapable of anything.
- Woolseyism: The Japanese children's songs were replaced with ones that would be familiar to Western readers, like "Twinkle Twinkle Little Star".
