Loser's redo: Transmigration in a novel - Chapter 17 Mana Drugs

Rokuhara Souta picked up a phone with a mysterious “Friendship System” installed. On that phone, he met an online friend with the nickname “Tokisaki Kurumi.”This online friend was a total roleplay enthusiast—her portrayal of Kurumi was so convincing it was almost eerie.Finding it amusing, Souta humored this hardcore chūnibyō (delusional teenager) and casually chatted with her.Since it was all fake anyway, he spoke without restraint, often throwing out flirtatious remarks just for fun.Until one day, he received an invitation from Tokisaki Kurumi to meet in person.And then… he transmigrated!In a filthy, bloodstained alley, dismembered human limbs lay strewn in the corners, the pungent stench of blood stinging his nose.Standing before Souta was Tokisaki Kurumi, fresh from a kill, smiling sweetly as she gazed at him…(Tentatively planned heroines include Kurumi, Oshino Shinobu, Military Princess(Re:Creator), Kamado Nezuko, Ereshkigal, Leticia… and more.)

This stands at the forefront of strategy guides to Life (a shitty video game)!
