Asumi Himawari- Ok so his first name's kanji read along the lines of pure love (it can also mean innocent peace) which kind of ties in the love and corruption and theme of the story and his last name just means sunflower, which his main motif and symbolisms hope, unconditional love and adoration, which all of them tie in his character. He represents hope, tends to love people unconditionally, and tends to give people the benefit of the doubt and second chances. Plus due to his blood, you can say he inspires some type of "adoration"
Kage Shiore- Well his first name Kage means shadow with first relates to his shadow powers, next it relates to how he was always in the shadow, especially of his younger sister, Hikari, also there's the contrast in with their names and it's also just because he's a gloomy guy. His surname means wilt, which refers him being in the shadow causing him to wilt and everything around him seem to wilt
Minato Ouka- Minato means harbor, which refers to the fact that she is Asumi's one harbor from everyone else's craziness since she compared to everyone is the most normal person and she secretly plans to save him from the Kami Game. Ouka refers to cherry blossoms which are her main motif, The ka part also can mean fulfill or come true which she'll do anything to make her dream of breaking the Kami Game become true. Also sakura blossoms refer to her mindset of life's short live it to max
Eri Sayuri- Eri means blessed prize which refers to the greed side of her character as well as her relationship with Asumi, with Kami, and all. Her surname means small lily, which her motifs are pink lilies that symbolize prosperity and abundance, which she likes to achieve
Collin Koi- Collin means young dog or pup which refers to his attachment to his youth and "purity", also it's a western name refering to his British heritance. Koi refers to love so putting that together can refer to young love or puppy love, which are his feeling towards Asumi
Mikoto Naruhito- With the kanji of her name, it means is charge and precious, Charge refers to her wrath and vengeful side, while precious refers to how she view Asumi, also Mikoto means Lord, Highness, which would be ironic seeing her timid and humble nature, It also was an archaic derogatory form of "you.", which actually fits better, It also rhyme with her twin sister, Mikoto. Naruhito means virtue and compassionate
Hanaki Akogare- Hanaki means flower tree or flowering tree which relates to the flower motifs in the series, ironically his flower motif is a Marigold that grow on the ground, his surname means longing or admire which implies his somewhat envious nature (eg. longing for things he can't have)
Emiko Junjo- Emiko means beautiful child or prized child, which prized child refer to her pride and drive to become one by the Kami Game. Junjo means pure and sincere which she isn't so that kind of ironic, also it the first name of a yaoi series named Junjou Romantic, that's kind of funny since she's one the "straight options"
Unzari Hachirou- Well Unzari isn't an actual japanese name but the word means tedious and dull, which describes his early life and is ironic to his actual personality. Hachirou means eight son, which could refers to ranking
Hikari Shiore- Hikari means light, which refer to her situtation with Kage since she's always respected and in the spotlight, though all this time having her talents cultivated caused other parts of her to wilt
Ran Ouka- means either orchid or lily, one meaning is also disturbed, which fit Ran well, Ouka refers to cherry blossoms, which just take Minato's idealogy of life is short, live it to the max and replace live to max with make such your goals are completed
Ai Kokoro- Her full name literally means love heart, which is ironic since she doesn't feel things like love
Nono Kokoro- His full name translate to hope/beg heart, which I guess can refer him hoping this game will end and the heart part is somewhat true despite his stoic disposition
Asagao Fuji- Asagao means morning glory which symbolises unrequited love and mortality, which refers to her Makoto Itouing Hanaki and her boyfriend, and her mortality come as her boyfriend pulled a Sekai Saionji on her. Fuji refers to wisteria that symbolism long life
Kosuke Fuyoko- With the kanji in his name it means amber and to help someone, amber was used to assure promises, which he doesn't and while does help people it's for his own selfish reasons. Fuyoko means winter child I actually know if that means some to him, maybe because he's cold-hearted
Makoto Naruhito- Makoto means sincere, true which is ironic because she hides behind her Yamato Nadeshiko mask, and Naruhito means compassion and virtue
Yuda Wanaka- Yuda means manly and hero which is kind of ironic because he's usually teased for being wimpy and a doormat, though he become one to save his niece and nephew. Wanaka means place of knowledge.
Chie Wanaka- Chie means wisdom with the addition of Wanaka meaning of place of knowlegde, ironically she is very naive and jaded of the world
Kotone Shiore- Kotone is usually a girl's name with the meaning harp sound or harp mausoleum of father, I guess the harp sound meaning refers worship, like almost worship like love of his wife Chie and mausoleum of father refers to him digging his own grave by his murderous ways catching up to him. Shiore refers to him making other wilt by using them for what he need and leaving afterwards
Dahilia Himawari- Dahilia refer the flower of the same name that symbolises elegance, inner strength, change, creativity, dignity, betrayal, dishonesty, and instability. While she isn't traitous though she got betrayed a lot and she's far from elegant or creative. But I guess she relates to change, dignity and instability. Change since her son and herself were the first to oppose and change the game. Dignity since she isn't ready to throw in the towel and Instablity since due to everyone hunting or betraying her, she can get a bit paranoid. Himawari carries the same meaning as her sons surname
Kiiro Suzuki- Kiiro mean yellows which symbolises optimistic, enthusiasm, hope, fun, and cheerfulness which match most of his personality, but some other factets I found were "when overused, yellow may have a disturbing effect and it is known that babies cry more in yellow rooms.", well that does fit his overprotective side (seeing he practically locked his son in their home and refused to let him out in fear Asumi might get killed or kidnapped) Suzuki mean bell tree, I guess the tree part refer to the similaties of another certain guy with a tree meaning in his name
Mamarou Eno- Mamarou means protect and defend, which is his main personality is being protective, He also share the same with the stalker from Perfect Blue. Eno means plains and civilian life, Which refers to their past life
Nanami Himawari- Nanami means seven seas, which refers to the number of normal participants and Himawari means Sunflower
