WILESTARS TEACHING METHOD

WILESTARS applies Affinity English, the original teaching method created by Manabu Tokimoto.

An interest in a world. A reason to understand its English.

Affinity English connects personal interests with the experience of understanding. WILESTARS develops that teaching approach through stories (novels, comics and anime), its character encyclopedia, games and music, so curiosity about its characters and world creates a reason to keep encountering English.

Explore the topics and English in each group of ten books
Books 1–10Introduction
Security and situations
Messages, impersonation, links, files, backups, accounts and signing out: choices close to everyday life.
English and reading
Subjects and verbs, negatives, questions, pronouns, short instructions, past actions, time and sequence. Read who asked for what, and what actually happened.
What to look for
Start with familiar messages, photos and screens. Return to the same passage to notice more of its information.
Books 11–20Introduction to foundations
Security and situations
Overlaid buttons, sharing, logs, interruptions, data movement, risk, urgent warnings, QR codes and senders. Book 20 introduces reporting an unusual event at work.
English and reading
Should, possessives, past continuous, quantities, future and conditional forms, purpose and question words. Book 20 uses the passive to identify actions and their targets.
What to look for
Follow the intended action and the actual result. Everyday decisions lead into workplace reporting.
Books 21–30Foundations
Security and situations
Information visibility, accuracy and availability; updates, records, multifactor authentication, layered measures, restoration, test scope, unattended sessions and keys.
English and reading
Present perfect, comparison, time, obligation, prohibition, permission, reasons, conditions, quantities and questions. A different workplace passage supports each reading question.
What to look for
Ask what a measure protects and what was actually checked. A completed test does not establish that everything is safe.
Books 31–40Foundations to team practice
Security and situations
Alert priorities, false positives, secret storage, evidence preservation, access, checks after repair, hashes, public and private keys, and TLS. Book 40 adds team recovery objectives.
English and reading
Combine possibility and fact, the passive, relative and conditional clauses, ability, permission and obligation.
What to look for
Matching content, verifying a source and receiving permission establish different things. Follow the evidence in the passage.
Books 41–50Team practice
Security and situations
Sources, signatures, versions and approval; urgent messages, observations, requests, notification changes, handovers, summaries, unclear instructions and policies.
English and reading
Read passive forms, tenses, relative clauses, requests, indirect questions, reported information, conditions and purpose.
What to look for
Communicate so the next person can decide and act. Keep the target, impact, confirmed results and remaining work even in a short summary.
Books 51–60Team practice to technical foundations
Security and situations
Evidence sources, operating notes, meeting decisions, remaining work, collaboration, consent, authority, shared evidence, linked records, repairs and resumption. Book 60 compares instructions with technical results.
English and reading
Use conditional clauses, passive forms, reporting tenses, relative clauses and perfect forms to read status and evidence.
What to look for
Track assignment, execution and verification, then consider what evidence supports a handover.
Books 61–70Technical foundations
Security and situations
Technical tests and actual use; input, output, secrets and build boundaries; restoration tests, revoked access, incident plans, authorization and inputs reaching databases, screens and networks.
English and reading
Use passive forms, conditional clauses and perfect forms to read targets, times, conditions and verified results.
What to look for
Connect a technical term to what it controls and where. Distinguish input handling from access control.
Books 71–80Technical foundations to analysis
Security and situations
Capacity, demand, uploads, repairs matched to causes, before-and-after changes, configuration and tests, scale, competition submissions and results, and integrations. Book 80 compares records and impacts.
English and reading
Read multiple constraints and results through conditional, passive and perfect forms. Book 80 introduces facts, hypotheses and priorities for further checks.
What to look for
Consider how to limit load and authority while preserving necessary use, rather than relying on stricter restrictions alone.
Books 81–90Analysis to design
Security and situations
Detection, observations, uncertainty, investigation material, comparing measures, proposals, agreements, handovers, symptoms and causes. Book 90 introduces protection, usability and continuity in design.
English and reading
Read uncertainty, limits, contrast, conditions and reasons. Keep conclusions within what the records support.
What to look for
Combine evidence, contradictory information and unanswered questions instead of deciding from one log or a striking number.
Books 91–100Design and improvement
Security and situations
Tabletop exercises, measurable objectives, alternative paths, switching and restoration, small trials, improvement, change management, regional and scale differences, acceptance and review.
English and reading
Integrate quantities, scope, time, dependencies and approval conditions using conditional clauses, the passive and perfect forms.
What to look for
Propose, check conditions, try and improve from the result. Book 100 compares measures across protection, use, continuity and verification, with reasons.
