A boy awakens on a desert island, unable to remember how he got there. He found the remains of a lifeboat with a few days’ worth of food, a survival kit, clothes and a trip schedule. Luckily, he soon discovers that one of his classmates, Chika, also is on the island. Together, the two catch fish, build a raft and try their best to survive and wait for help – not to mention try to remember how they came to be on the island.
Akira Sengoku and his class were traveling home from a field trip aboard Flight 357 when the plane mysteriously crashed, leaving them stranded on a hostile, prehistoric island. In this place, extinct and colossal animals run wild, quickly devouring many of the survivors and leaving the rest to fight for their lives. Alongside his childhood friend Rion and other classmates, Akira will struggle to survive in this impossible place against all odds.
Cage of Eden and Let's Lagoon are similar because of the plot. Kids get stranded on an island and have to survive. Both the main characters, who are boys, are looked up to and relied on for survival. Tensions start to flare when newcomers join the island or group and the drama starts. Though Cage of Eden is a bit more brutal and heart racing and Let's Lagoon is slice of life, the question still remains, "Will they ever get off the island alive?"
I'm not a huge fan of Eden no Ori, but both it and Let's Lagoon have a combination of survival and blatant (and frankly, irritating) ecchi. Eden is far more focused on people getting eaten while Lagoon is more of a realistic, quiet tale, but fans of one will likely enjoy the other.
These two are very similar on many levels. They are both survival manga that have adventure. They also have a very similar plot and supernaturalness to them. If you liked one, you will definitely like the other.
Three ‘believers’ – two men and a woman – live on a deserted island as part of a special program. Their goal is to co-habitate and learn how to purify themselves from the outside, evil world under the teachings of Master. From day to day they remind themselves of his words and purge their vile thoughts, but soon two of them begin to discover a better, yet ‘wrong’, way to pass the time. However, Master’s teachings are absolute, and their actions won’t go unnoticed...
Let's Lagoon and Believers are definitely not the best recommendation pair, but it's a relatively decent one. Both - at least in part - revolve around a group of people stranded on an island and/or have survival aspects. However, Let's (so far) has stayed fully entrenched in survival mode, while Believers deviates wildly in its plot. Also, Let's is mostly ecchi, while Believers is very borderline H.
When the infected approached Rei and Takashi's school, it led to a gruesome blood bath that left the majority of students and staff dead or turned into the zombie-like monsters that have spread throughout the world. Together with a handful of other survivors, Rei and Takashi set forth to find their families in a world that is rapidly detoriating. Governments have collapsed, the killer disease is out of control, and people everywhere are trying their best to simply live through each day...
Highschool of the Dead is based around zombies and people tend to get killed, while Let's Lagoon is more of a quiet tale of life on an island. What do they have in common? A combination of survival and ecchi, without an excessively harrowing survival tone like other series out there.
Recently the number of attempted suicides have increased dramatically, straining the health care system. To combat this problem, those who try to take their life are placed on a special island where they must live out their days, while the rest of the world believes them to be dead. Some respond by immediately committing suicide while others decide to try to live; but with no supplies doing so will be difficult. Now, this group of strangers must work together to survive on Suicide Island, or die trying.
Both of these are survival stories that take place on smaller islands. The stories are totally different, but in the end it always comes down to the basic needs of survival. Let's Lagoon is not as dark as Suicide Island but still has it's share of seinen. If you like survival manga these are both great.
Mishima is a salary man who's constantly away from his wife and child due to his grueling, overtime-heavy job. After being stuck in the office on the eve of his son's birthday, Mishima boards the train with remorse and ponders his life. Before he can return home, however, a 7.0 earthquake strikes, crippling the train and leaving its passengers helpless. Mishima now finds himself as the appointed leader of a group of survivors who want nothing more than to stay alive. Together, they will try to make their way to the surface, but starvation, cave-ins and other fatal obstacles stand in their way...
Unlike most other survival manga which tend to be based on supernatural or fantastical plot points, Metro Survive and Let's Lagoon focus on realism (for all of MS, and at least for the current 5 chapters I've read of Let's Lagoon). If you're into realistic survival, definitely check out these titles.
