Reborn In Another World As A Spirit Familiar - Chapter 255: Prankster

Suddenly a high school student Subaru Natsuki has been summoned to another world on the way back from the convenience store. With the biggest crisis of his life being summoned to another world and no sign of the one who summoned him things become worse when he is attacked.

This crossing is so strange, death crossing, game crossing, etc. are probably barely acceptable, but why can you cross even if the fish tank is broken?

and actually passed through the magic tree in “OVERLORD” that is said to be able to destroy the world?

No! It is sad enough to regenerate into a plant. The protagonist, Ainz Ur Gong, the undead king, has also accepted the adventurer’s guild mission and wants to kill me!

I want to change my destiny! Live! I want to-surrender!

Ainz: Since he has accepted the job commission from the Adventurer’s Guild, deliberate failure is detrimental to the prestige of Ainz Ul Christine (the “surrender” button has been deducted)

actually died as soon as he crossed, but there is still a chance to return~ from the beginning of the magic tree to this world.

I must change my destiny this time! Live!

- Description from novelbuddy

He wants indoor plumbing. They think he’s conquering the world.Arthur was a genius engineer on Earth, capable of optimizing global logistics and automating entire factories. But he lacked one thing: common sense. Now, reincarnated as Arthur von Pendelton, the six-year-old son of a powerful Duke in a medieval fantasy world, he faces his greatest challenge yet: Drafts.Armed with the T.E.C.H. Interface (Trans-Epochal Construction Heuristic), Arthur can analyze magic like code and build modern technology from scratch. His goals are simple: Double-glazed windows, hot showers, and a toaster that doesn't burn the bread.But there is a problem. The people of this world don't understand engineering.He builds a high-pressure boiler for a bath; his father thinks it’s a “Dragon-Breath Siege Weapon.”He creates a hydroponic garden; the local church declares him the God of Harvest.He ignores a Princess's flirting to analyze the thread count of her dress; she thinks he is playing “hard to get.”Follow Arthur as he accidentally industrializes a kingdom, terrifies his enemies with home appliances, and remains completely oblivious to the fact that he is becoming the most powerful man in history.All he wanted was a warm bath.

Reincarnated into the muddy guts of a cursed swamp as a tsetse fly, former office worker and master-level cynic Buzz Windbreaker quickly discovers that survival is both absurd and magnificent. The air is thick with poison, the predators are many-limbed and spell-woven, and the prey? Just as desperate as he is.Yet with every drop of blood he drains from beast, beastkin, or unlucky mortal, Buzz unlocks fragments of an ancient arcane lattice that spirals beneath the skin of the world itself—a system of runes, incantation spirals, and primordial energy flows forgotten by even the highborn mages.His evolution isn't just physical: it is architectural. Each new form is built like a spell—symmetrical, efficient, cruel. Wings shimmer with sigil arrays. Proboscises become siphons of mana and memory. Legs are sharpened to runic blades. Jokes sting. Death stings harder.Soon, Buzz isn't just hunting. He is ascending.
