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